Marsupials are mammals whose young develop in pouches. Examples include kangaroos, koalas, wombats, and Tasmanian devils. Kangaroos have strong tails and legs to jump long distances. Koalas mainly eat eucalyptus leaves and sleep 16-18 hours a day due to low metabolism. Wombats dig burrows with claws and teeth. Tasmanian devils are the largest carnivorous marsupials and get their name from loud fighting noises. While Australians may joke about dangerous "drop bears," these do not actually exist.

Skull typpes
This document summarizes the different types of skulls found in reptiles:
- Anapsid skulls, found in primitive reptiles and turtles, have no temporal fenestrae.
- Euryapsid skulls, found in marine reptiles like plesiosaurs, have a single pair of fenestrae high on the skull.
- Parapsid skulls, seen in ichthyosaurs, are similar but with additional bones bordering the single fenestrae.
- Diapsid skulls, common in living reptiles and dinosaurs, contain two pairs of fenestrae on each side of the skull.
- Synapsid skulls, seen in early mammal-like reptiles
Presentation on aquatic mammals
The document discusses the aquatic adaptation of mammals. It acknowledges those who helped with the seminar topic. The contents include introduction, adaptation of aquatic mammals, modification and loss of original structures, development of new structures, types of aquatic mammals, and conclusion. It describes various anatomical modifications that aquatic mammals undergo, such as streamlined bodies, flippers, valvular nostrils, large lungs, blubber, and tail flukes to adapt to aquatic living.
Origin and Evolution of Mammals
The document discusses the origin and evolution of mammals. It describes two main theories for the ancestry of mammals - through amphibians or reptiles. While amphibian ancestry was proposed, reptilian ancestry is now widely accepted based on fossil evidence. Many characteristics of early mammal-like reptiles called therapsids were mammalian. True mammals first appeared in the Jurassic period but remained small until after the extinction of dinosaurs. When ecological niches opened up in the Cenozoic era, mammals underwent adaptive radiations into various forms through modifications of limbs, teeth and other features for different habitats like trees, ground, burrows, water and air. Convergent evolution also led to similarities between unrelated mammals adapting to the same nic
Parental care in amphibians and reptiles
Any form of parental behavior that appears likely to increase the fitness of the parent’s offspring.
Parents of some animals go to great lengths to increase their offspring’s survival prospects by protecting them from predators, food shortages, desiccation, and a range of other environmental hazards.
First off all they decide the oviposition site.
Any place where small puddles of still water form can provide a suitable nesting site. Sites range from potholes, tapir tracks, and large leaves to human made ditches, road ruts, and even plastic bowls
Rheobatrachus females brooded tadpoles in their stomachs, and the young emerged from the females
In case of moor frogs, males stay to guard the clutch. They attack anyone who
approaches it! They do not leave the post until tadpoles hatch. Only then, starving fathers
go to land and may eat well.
CLASSIFICATION OF MAMMALS
Mammals are classified into 5420 species within 152 families and 29 orders. The two subclasses are Prototheria and Theria. Prototheria contains monotremes like platypuses and echidnas that lay eggs. Theria contains marsupials in the infraclass Metatheria that give birth to immature young developing further in pouches, and placentals in Eutheria that give live birth to mature young. Marsupials include opossums and kangaroos, while placentals make up the majority of mammal species and include humans, whales, bats and more. Classification systems continue to evolve as new genetic and fossil evidence is discovered.
Fish Migration
Fish migration occurs for various reasons such as finding new habitats, feeding, reproduction, and escaping predators. There are several types of fish migration defined by distance, direction, and purpose. Anadromous fish migrate from salt water to fresh water to spawn, like salmon, while catadromous fish do the opposite, migrating from fresh to salt water to spawn. Potamodromous fish migrate within fresh water systems. Oceanodromous fish migrate long distances within salt water environments. Physical, chemical, and biological factors influence fish migration patterns. Migration allows fish to access new food sources and breeding habitats but also carries risks.
Birds
- Birds evolved from reptiles and Archaeopteryx possessed both reptilian and avian features. Key avian traits include feathers, hollow lightweight bones, beaks, endothermy, and amniotic eggs.
- Birds have highly specialized organ systems for flight including strong heart and respiratory systems. Their feathers provide insulation and flight abilities.
- There are many orders of birds with varied traits like waterfowl that are aquatic, owls with keen vision and hearing, and songbirds that communicate through song.
Parental care in mammals
Parental care involves investment from parents to increase offspring survival and fitness. In mammals, most care is maternal, involving lactation. Only 6% of mammals show biparental care where monogamous males and females provide care. Paternal care can involve protecting young from predators and helping with growth. For artiodactyls like deer and antelopes, females are the sole caregivers through lactation. They use hiding or following strategies to protect vulnerable young until independent.

Aquatic adaptations in birds and mammals
This document discusses the aquatic adaptations of birds and mammals. It describes morphological, anatomical, and physiological adaptations that allow birds like ducks and geese to live in aquatic environments. These include webbed feet, waterproof feathers, nasal flaps, and salt glands. Mammals like platypuses also have adaptations for aquatic life such as webbed feet and electrosensory bills. The document concludes that nature continues to amaze with the variety of adaptations that allow species to exploit different environments.
Diversity Of Mammals Placental Mammals
Placental mammals exchange nutrients and gases between the mother and embryo through the placenta. This includes humans and most other mammals. Mammals are divided into groups based on traits like number of toes and diet. Carnivores like bears eat meat but can also consume plants. Cetaceans like whales are carnivorous marine mammals. Bats are the only mammals that can truly fly and feed on insects, fruit, and nectar. Rodents have sharp front teeth and eat plants and wood. Primates like lemurs have complex behaviors and brains unlike other animals. Proboscideans like elephants have trunks.

Rotifers phylum
Rotifers are microscopic aquatic animals of the phylum Rotifera. Rotifers can be found in many freshwater environments and in moist soil, where they inhabit the thin films of water that are formed around soil particles.
Parental care in amphibians
Parental care is common among amphibians, with 18% of salamander species and 6% of frog and toad species receiving care from both parents. Amphibians exhibit various forms of parental care including building nests, transporting tadpoles, carrying eggs attached to their bodies, and giving live birth (viviparity). In frogs, parental care involves nest building and guarding of eggs, transporting tadpoles, or carrying eggs in pouches or stomachs. In salamanders, both parents may coil around and guard eggs or exhibit viviparity by retaining young in the uterus until metamorphosis. While methods vary across the three amphibian classes, parental care helps increase offspring survival.
Animal behaviour
Behavior is everything an organism does in response to stimuli from both the external environment and internal bodily states. It includes innate behaviors that are genetically determined and critical for survival, such as feeding, grooming, and reproduction, as well as learned behaviors influenced by environmental factors. The scientific study of animal behavior is called ethology and focuses on understanding behavior in natural habitats and social contexts.

Amphibian history notes
The document discusses the characteristics and evolution of amphibians. It notes that lobe-finned fish were ancestors of amphibians, which allowed them to move between bodies of water. There are approximately 4,000 known amphibian species classified into three orders. Amphibians are characterized by their permeable skin, three-chambered hearts, and typically having an aquatic larval stage before transforming into terrestrial adults.
Swim bladder
The document discusses the swim bladder, or air bladder, of fish. It is an internal gas-filled organ that contributes to a fish's ability to control buoyancy. There are two types - physostomous, which is directly connected to the digestive tract, and physoclistous, which is not connected. The basic structure includes a sac-like shape with two layers, an epidermis and endodermis. The swim bladder varies in shape and size between fish species and allows fish to rise and sink in water by increasing or decreasing the volume of gas inside without changing mass. Its key functions are to act as a hydrostatic organ, adjustable float, aid in respiration, produce sound, and maintain the fish's
Flightless bird
This document summarizes flightless birds. It begins by defining flightless birds as belonging to the superorder Palaeognathae, characterized by a Palaeognathous plate. These birds are flightless, with small heads, rudimentary wings, and well-developed legs adapted for running rather than flying. The document then discusses four orders of flightless birds - ostriches, emus, cassowaries, and kiwis. Examples are provided for each, describing their physical characteristics and habitats. In closing, the document briefly mentions penguins as another type of flightless bird found in cold southern climates.
Characteristics of mammals
Mammals share 7 key characteristics: (1) making milk, (2) breathing air, (3) being endothermic, (4) having hair, (5) having specialized teeth, (6) sexual reproduction, and (7) having large brains. Placental mammals make up the majority of mammals and their embryos develop inside the mother's uterus, receiving nutrients via the placenta. Living placental mammals are divided into 11 main groups including insectivores, rodents, carnivores, hoofed mammals, primates, and cetaceans.
Animal distribution zoogeo
Animals are not uniformly distributed across land and water due to factors like climate, food availability, shelter, and other species. Their distribution can be categorized as continuous, discontinuous, endemic, isolated, or bipolar. Continuous distribution means worldwide presence. Discontinuous distribution occurs when habitat is broken up, such as by oceans or changing land masses. Endemic distribution confines species to particular regions. Isolated and bipolar distributions restrict some animals only to specific isolated areas like Australia or polar regions.
Parental care in Amphibians
Parental care in amphibians provides benefits to offspring survival. There are various types of parental care exhibited by different amphibian species, including selecting protected nesting sites, defending eggs or territories, directly transporting tadpoles to water, gluing or carrying eggs attached to the body, and even viviparity in some species. Parental care improves offspring chances of survival by protecting eggs from predators and ensuring young amphibians safely reach water once hatched.
Mammals
Mammals evolved from reptiles called Therapids during the Mesozoic era. They increased rapidly during the Cenozoic era. Mammals are characterized by having hair, mammary glands to feed young, and being warm-blooded. They are classified into monotremes, marsupials, and placentals. Placental mammals carry young to term in the uterus. There are 19 orders of mammals including rodents, bats, whales, carnivores, even-toed and odd-toed ungulates, primates, and more. Each order has distinct characteristics related to their evolution, habitats, diets and behaviors.
Classification of Mammals
This document discusses the classification of mammals. It begins by covering the subclass Prototheria, including the characteristics and two surviving orders - Monotremata which includes the platypus and echidnas. The subclass Theria is then discussed, including the infraclass Metatheria which contains the order Marsupialia. Key details are provided on the characteristics of marsupials, including their short gestation periods and young rearing their young in pouches. Examples like koalas and opossums are provided. Their geographic ranges and habitats are also summarized.
MIGRATION OF FISHES
1) Fish migration involves the movement of fish from one area to another, usually for feeding or breeding purposes. Several species migrate long distances for spawning and feeding, including cod, herring, salmon, eel, and tuna.
2) There are different types of migration including alimentory (for food/water), gametic (for reproduction), climatic (for suitable climate), and osmoregulatory (for osmoregulation). Fish can migrate through drifting with water currents, random locomotory movement, or orientation swimming in a particular direction.
3) Migration patterns vary between species and include diadromous (between fresh and salt water), potamodromous (within fresh
Diversity Of Mammals Monotremes
Monotremes are a special group of mammals that share characteristics with reptiles. They lay soft-shelled eggs and incubate them for 10 days like reptiles. Monotremes also have a cloaca, a single bodily opening, like reptiles. There are only two monotreme species - echidnas, which are spiny anteaters found in Australia and New Guinea, and have either short or long beaks, and platypuses, which are one of the few poisonous mammals and live in water hunting for food.
Protochordates
Protochordates have two subphyla: urochordates and cephalochordates. Urochordates include sea squirts and related invertebrate groups, while cephalochordates are represented by amphioxus. Amphioxus is considered the most basal chordate and shares several anatomical similarities with the larval stage of lampreys, including a dorsal nerve cord, brain, myomeres, and filter feeding behavior, though amphioxus lacks a heart and organized kidney.

Class Mammalia is characterized by having mammary glands, hair, a diaphragm, and three middle ear ossicles. Mammals also have a heterodont dentition, sweat, sebaceous, and scent glands, a four chambered heart, and a large cerebral cortex. There are three main types of mammals: monotremes like the platypus and echidna, marsupials which have a pouch like kangaroos, and placental mammals which give birth to young that develop fully inside the mother like humans. Gestation periods vary greatly among mammals from 16 days in mice to 640 days in African elephants. Mammals can decrease their metabolic rates through torpor,
Mammals, birds, fish and amphibians (ScienceandEnglish.com)
Mammals are vertebrates that have fur or hair, breathe with lungs, give live birth, and drink milk from their mothers as babies. They come in a wide range of sizes from the smallest mice to the largest whales and elephants. Mammals can walk on four legs or have flippers to swim and are herbivores, carnivores, or omnivores depending on their teeth.

This document discusses the characteristics of mammals. It lists several common mammal examples like elephants, dogs, giraffes, hippos, sheep, and cats. The key characteristics of mammals are that most have four legs, have hair, breathe with lungs, have internal bones and are vertebrates, give live birth, and babies drink mother's milk.
Embryogenesis
1. Embryogenesis begins with fertilization of an egg cell by a sperm cell, forming a zygote. The zygote then undergoes cleavage, dividing into multiple cells while maintaining the same size.
2. After the 7th cleavage division forming 128 cells, it is called a blastula. Cells then migrate inward during gastrulation, forming the endoderm, mesoderm and ectoderm germ layers.
3. The endoderm forms the inner lining of the digestive system. The mesoderm forms muscles, bone, blood and other tissues between the endoderm and ectoderm. The ectoderm forms the outer layer including the skin and nervous system.
Mammalogy Lab 3
The document outlines the taxonomy of different mammal orders and families, organized into subclasses. It discusses egg-laying monotremes like echidnas and platypuses, as well as various orders of marsupials including opossums, kangaroos, wallabies. It also mentions armadillos and various anteaters and sloths. The taxonomy shows the relationships between the different mammal groups and families within the subclasses of Prototheria, Metatheria, and Eutheria.
Comparative Anatomy - Reproductive System
The document provides an overview of the reproductive systems of vertebrates. It describes the general structures and functions of the male and female reproductive systems. Key points include: 1) The female system produces eggs and houses the embryo, while the male system produces sperm. 2) Structures such as ovaries, oviducts, uterus, and vagina are present across vertebrate classes with some variations. 3) Testes, ducts and accessory glands are the main male structures. 4) Fertilization and copulation methods vary between external in frogs to internal in mammals. 5) The cloaca is modified in different groups, remaining primitive in some and separating functions in others like mammals.
The placenta
The placenta develops from fetal and maternal tissues to function as the respiratory, nutritive, excretory, barrier and endocrine organ of pregnancy. It transfers oxygen, nutrients and waste between the mother and fetus. The placenta can develop abnormalities in its shape, size, position or adhesion to the uterine wall which may cause complications like preterm birth or hemorrhage. Placental lesions like infarcts may also occur due to conditions like hypertension.
Kangaroo Reproduction
A presentation on reproduction in kangaroos including embryonic diapause, tyranny of the estrous cycle, and forelimb vs hindlimb development
Placenta development
The document summarizes the development and anatomy of the human placenta. It begins by defining the placenta and outlining its objectives. It then describes the development of the placenta from the chorion and decidua, the structures of the mature placenta including the chorionic plate, basal plate, intervillous space and villi, and the maternal and fetal circulations that occur through it. Finally, it discusses placental aging and the degenerative changes that occur over the course of a pregnancy.

A Simple Review of Opossums
The opossum is a marsupial mammal that is well-adapted to survive harsh winters in North America despite originating from warmer climates. It has developed behaviors like playing dead to evade predators and grows only a thin layer of fat instead of a winter coat. Opossum mothers give birth to underdeveloped young that crawl into her pouch to nurse and develop further. Though slow-moving, the opossum's prehensile tail and ability to climb trees aids its survival against threats on land.
Tasmanian devil book for ms.wagner
The Tasmanian devil will typically mate in March and give birth to 2-3 young in April. The newborn babies will spend their first 4 months in their mother's pouch before beginning to explore outside the pouch at around 4 months old. They will nurse until around 5-6 months and become independent at 8 months. Tasmanian devils reach sexual maturity at around 2 years old.
Group F
The toucans and chimpanzees were constantly competing for food in the trees, with the larger groups of chimpanzees usually dominating. The toucans began to die off until one toucan had the idea for the group to migrate to South America to find a new home without competition. In Africa, lions were hunting zebras and buffaloes for food, threatening to drive the herds to extinction. Eventually, humans intervened by relocating some of the animals to zoos and protected areas, ensuring the survival of both predator and prey species.

The toucans and chimpanzees were constantly competing for food like fruits from the trees. Since the chimpanzees lived in larger groups, they usually won the fights over food. With little food available, the toucans began to die off. However, one toucan had the idea for the group to migrate to South America to find a new home without competition from the chimpanzees.
In Africa, lions were hunting buffaloes and zebras for food. As the lion population grew, they threatened the survival of the buffalo and zebra herds. Living in large groups helped the prey animals defend themselves but also meant the loss of an entire herd if one was attacked. With less

The document discusses conflicts over food between different species in Africa, including chimpanzees and toucans, lions and zebras/buffaloes. The toucans were outcompeted by chimpanzees for fruit and many died, so some toucans migrated to South America. Lions hunted zebras and buffaloes but their numbers were declining due to lack of food, so humans intervened by taking some animals to zoos to save the species.

World's Largest Marsupial
The red kangaroo is the world's largest marsupial. It can leap 25 feet and hop at speeds up to 35 miles per hour using its powerful hind legs and tail for balance. While newborn joeys are tiny, under an inch long, they develop in their mother's pouch, nursing and growing until big enough to hang out of and eventually stay out of the pouch. Red kangaroos travel together in large mobs and use hopping as their primary mode of transportation across the Australian grasslands, shrublands, and deserts where they consume vegetation and can go long periods without drinking.
Australian animals
Australia is home to many unique animal species. Some of the major animals discussed include:
- Kangaroos, which move by jumping and carry their young in pouches.
- Koalas, which spend most of the day sleeping in eucalyptus trees.
- Cassowaries, large flightless birds with sharp claws that can be dangerous to humans.
- Wombats, short-legged burrowing marsupials that resemble badgers.
- The platypus, a venomous mammal that lays eggs and has a duck-bill and webbed feet.
- The Tasmanian devil, a carnivorous marsupial known for its loud screams and cannibalistic tendencies
Animal
The document provides information about various African animals, including kangaroos, ostriches, elephants, giraffes, lions, and monkeys. It describes their physical characteristics, habitats, behaviors, diets, and other attributes. For example, it notes that kangaroos live in Australia and can travel up to 60 km/h, ostriches are flightless birds found in Africa that eat grass and small animals, and elephants have large tusks and ears and can weigh up to 7,500 kg.
Wild animals and unique birds
Tigers are large carnivores that live in forests and grasslands across parts of Asia. They have distinctive orange fur with black stripes and hunt alone, preying on deer, wild pigs, and other medium-sized animals. There are currently eight subspecies of tiger, three of which are extinct and one nearly extinct, as human activities have severely reduced their historical range.

Each letter of the alphabet is accompanied by an animal name starting with that letter along with 1-2 sentences of facts about that animal. Some animals covered include ants, bats, cats, dogs, elephants, fish, giraffes, horses, ibex, jerboas, and kelpies. The book provides basic information about each animal in a simple format intended for young readers to learn.
Unit2essay-Australian Animal Adaptation
Native Australian species such as marsupials and monotremes flourished due to Australia's geographic isolation which allowed them to evolve without competition from other land animals. Marsupials like kangaroos and wombats thrive through easy to access diets and protection in pouches, while monotremes such as echidnas and platypuses lay their eggs in protective aquatic or burrow environments. However, introduced species like rabbits and foxes have driven the decline of native species by outcompeting them for resources as they lacked natural predators in Australia. Both native and introduced species have adapted to the Australian environment through traits like herbivorous diets, burrowing, camouflage or defense mechanisms.

Bat report for ariel hyers
Bats are omnivorous mammals that eat plants, animals, insects, and small vertebrates. They are nocturnal hunters that use echolocation to navigate and find prey in darkness. While most bat species eat insects, some tropical bats eat fruit and nectar, and three species drink blood. Bats face threats from habitat loss as forests are cut down and caves destroyed, as well as direct killing from humans for food, medicine, and out of misunderstanding. Conservation efforts aim to protect bat populations and combat myths that contribute to their endangerment.
Endangered Animals
The document discusses several endangered animal species, including dolphins, elephants, pandas, whales, and tigers. It provides details on their physical characteristics, lifespan, diet, breeding behaviors, and threats they face. Specifically, it notes that dolphins live in pods and use echolocation to hunt, elephants can weigh up to 15,000 pounds, pandas mainly eat bamboo and give birth to 1-2 cubs, whales can grow over 100 feet long and live 20-30 years, and tigers normally have 3-4 cubs at a time. The document concludes by calling for help to save these endangered animals.
Tammys Keynote..
Tasmanian devils are the largest carnivorous marsupials in the world. They are stocky animals around the size of small dogs, with black fur and white markings. Tasmanian devils are mainly scavengers but will also hunt smaller animals and prey. They have large home ranges that overlap with other devils as they search for food at night. In recent decades, a contagious facial tumor disease has spread among devil populations and threatens their long term survival, with the species now listed as vulnerable.
Essay On Koala
The document provides information about koalas, including their origins in Australia, habitat, behaviors, and mating/birthing processes. Koalas originated in Australia and were discovered in 1798. They inhabit trees and eat eucalyptus leaves. During mating season, the male koala's call sounds like a saw cutting through wood. Newborn koalas are tiny and live in their mother's pouch for months.
Porcupines
Porcupines are large rodents that can weigh up to 18 kg and be over 1 meter long. They live in North America and use their quills for protection from predators like foxes, dogs, and bears. Porcupines spend time in trees and dens, eat plants and bones, and have 30,000 quills that can be used to defend themselves.

18 3 Powerpoint[1]
The document discusses the three domain system and six kingdom system of classification. The three domains are Bacteria, Archaea, and Eukarya. Bacteria and Archaea are prokaryotic and unicellular, while Eukarya includes protists, fungi, plants, and animals which are eukaryotic. The six kingdoms are further divided within these domains.
Chordates
The document discusses nonvertebrate chordates and fish. It states that tunicates and lancelets are the two groups of nonvertebrate chordates. It defines chordates as animals that have a nerve cord, notochord, pharyngeal pouches and a tail extending past the anus. The document also notes that fish are aquatic vertebrates that mostly have paired fins, scales and gills, and that the evolution of jaws and paired fins were important developments for fish. It discusses adaptations for aquatic life in fish and classifies all living fish into three groups: jawless fish, cartilaginous fish, and bony fish based on their internal structure.
18 1 Classification
Taxonomy is the discipline of classifying organisms and assigning each a universally accepted scientific name using a binomial nomenclature system consisting of genus and species. This classification system organizes organisms into a hierarchy of taxa including genus, family, order, class, phylum, and kingdom based on their characteristics and evolutionary relationships.
Elements Of Behavior
1) The document discusses different theories of how animals learn and behave, including innate behavior, stimulus-response learning, and different types of learned behavior like habituation, classical conditioning, operant conditioning, and insight learning.
2) It provides examples of each type, like how animals might respond with defense, escape, or attack behaviors innately in response to being spooked in the wild.
3) The document also discusses famous experiments that helped establish theories of learning, like Ivan Pavlov's work with classical conditioning and B.F. Skinner's operant conditioning experiments using a "Skinner Box."
Primates And Human Origins
1) Fossil discoveries have shown that human-like creatures lived hundreds of thousands to millions of years ago, but the exact origins of humans is still unclear.
2) Early hominids such as Sahelanthropus tchadensis from 6.75 million years ago may have been human ancestors or more closely related to other apes.
3) Over millions of years, hominids became more upright, less dependent on trees, developed tools and art, and migrated from Africa to other parts of the world, including Neanderthals who lived in caves.
4) While theories abound, the exact reasons for hominid migrations and developments are unknown.
What Is An Animal 13 1
Animals are living things that cannot make their own food, digest food instead, and have many cells with nuclei to move around. They can be divided into vertebrates that have backbones and invertebrates without, with body structures arranged radially in a circle or bilaterally along a line.
Intro To Animals
The animal kingdom is extremely diverse, with some animals being microscopic while others are several meters long, living in various environments from inside other bodies to the open sea. Animals are multicellular eukaryotes that lack cell walls and carry out essential functions like feeding, respiration, circulation, excretion, response, movement, and reproduction to maintain homeostasis. The kingdom is divided into invertebrates, which lack backbones, and vertebrates, which have backbones.
Reptiles Juju
Reptiles are vertebrates with scaly skin, lungs, and terrestrial eggs that allow them to live fully on land. They evolved from amphibian ancestors and came to dominate during the Triassic period, though most dinosaurs went extinct at the end of the Cretaceous period due to volcanic eruptions and an asteroid impact. Modern reptiles include snakes, lizards, crocodilians, turtles, and the tuatara; they regulate their body temperature through environmental interactions, have two-chambered hearts, and reproduce through internal fertilization or ovoviviparity. Many reptile species are endangered due to habitat destruction and overhunting.
Birds
Birds are feathered, winged animals that evolved from extinct reptiles. They have several adaptations for flight including lightweight bones, strong chest muscles and aerodynamic feathers. Birds maintain a constant high internal temperature through high metabolisms and efficient respiratory, circulatory and digestive systems. Their feeding process involves using a muscular gizzard to break down food and a crop to store and moisten it.
Reptiles Life Science 15 4
Reptiles first appeared nearly 280 million years ago and include turtles, crocodiles, and lizards and snakes. They have dry scaly skin, lay amniotic eggs with membranes to protect embryos, and show little maternal care once eggs are laid. Modern reptiles descended from early reptiles and vary widely in size, shape, color, habitat, diet, and behavior.
14 3 Arthropods
The document provides information about various arthropod classes including Crustacea (crabs and lobsters), Myriapoda (millipedes and centipedes), extinct Trilobita class, Chelicerata class including horseshoe crabs and arachnids such as spiders. It describes their physical characteristics, habitats, behaviors, life cycles and feeding habits.
Reptiles 31
Reptiles evolved from amphibian-like ancestors and have diversified into many forms like turtles, snakes, and dinosaurs. Reptiles have lungs and lay shelled, amniotic eggs to protect embryos from drying out. The four surviving groups of reptiles are lizards and snakes, crocodilians, turtles and tortoises, and tuatara. Birds are reptile-like animals that maintain a constant internal temperature through generating their own body heat from metabolism, unlike reptiles which rely on external heat sources.
