Amphibians are vertebrates that typically live both on land and in water. They evolved adaptations like stronger bones and limbs that allowed them to move on land while still having lungs and gills. There are three main groups of amphibians - salamanders, frogs and toads, and caecilians. Amphibians have defenses like poisonous skin secretions and camouflage to protect themselves from predators.

Early Chordate introduction Notes
The phylum Chordata is characterized by four defining features in its members: 1) a dorsal, hollow nerve cord, 2) a dorsal notochord to support the body, 3) a post-anal tail at some stage of development, and 4) seven pharyngeal clefts at some stage of development. The phylum is divided into three subphyla, with the subphylum Vertebrata further divided into 10 classes that include mammals, birds, reptiles, amphibians, and various fish classes.
Amphibians
Amphibians are vertebrates that live both on land and in water, starting their lives as aquatic larvae and transitioning to terrestrial adults. They use camouflage, toxins, and bright colors to protect themselves from predators. As tadpoles, they feed using filters, and as adults they eat just about anything they can catch and swallow. Their lungs, tympanic membranes, and nictitating membranes allow them to survive on land and in water. The three main groups are salamanders, frogs and toads, and caecilians, though amphibian populations are declining globally.
Echinoderms test review
This document contains 100 trivia questions and answers about echinoderms organized into categories - How Many, What's That, Spiky, Nuts & Bolts. The questions cover topics like the names of body parts of sea stars, sea urchins, and sea cucumbers. They also ask about the number of echinoderm species, what eats sea cucumbers, and the types of symmetry and systems that echinoderms have.
Frogs and toads
Frogs and toads are both amphibians that live on land as adults after being born as tadpoles in water, but frogs have slimy skin, webbed feet for jumping and swimming, and live near water while toads have dry, warty skin, shorter legs for walking on land, and live farther from water. The document provides information about the differences and similarities between frogs and toads through a Venn diagram activity for students.
Sea Urchin & Sea Cucumber Notes
This document discusses sea urchins and sea cucumbers. It notes that sea urchins have spines for protection and come in many varieties, some with long spines and others with short stout spines. Sea biscuits and sand dollars are flattened sea urchins that live in sandy areas. Keyhole urchins have slits that allow water flow to prevent being washed away. Sea cucumbers live on the sea floor, eat sand and organic material, and are an important food source and industry in some areas like the Galapagos Islands.
Agnathan Fish Notes
The document discusses early fish evolution, including jawless fish like hagfish and lampreys. It describes key characteristics of hagfish, including that they have no backbone but are still considered vertebrates. It then discusses different classes of jawless fish like lampreys and ostracoderms, which were early armored fish. Placoderms followed as the first jawed fish.
Frog Anatomy and morphology
Amphibians can live both on land and in water, having evolved from lobe-finned fish. Frogs are a type of amphibian that undergo a metamorphosis from an aquatic larval stage to a terrestrial adult. As cold-blooded animals, frogs have adaptations like thin, moist skin and the ability to hibernate or estivate to survive in changing environments.
All about frogs!.ppt
Frogs are amphibians that live both on land and in water. They have short bodies, webbed fingers or toes, protruding eyes, and lack tails. Most species live in rainforests and all over the world except Antarctica and some islands. Many frogs use camouflage to hide and some can change colors. Poisonous frogs often have bright colors and obtain toxins from their diets to deter predators. Frogs eat insects and small animals, going through a life cycle from egg to tadpole to adult. They communicate through loud calls to find mates and mark territory.

Intro to Echinoderms Notes
The document discusses the phylum Echinodermata, which includes sea stars, sea urchins, sea cucumbers, and crinoids. Echinoderms are radially symmetric as adults and have a water vascular system instead of a circulatory system. This water vascular system allows them to move, feed, and exchange gases via tube feet that extend from their bodies. The four classes of echinoderms are discussed: Asteroidea (sea stars), Echinoidea (sea urchins), Holothuroidea (sea cucumbers), and Crinoidea (crinoids/sea lilies).
The amazing platypus
The platypus lives in eastern Australia in rivers, streams, and logs. It has a duck-like bill, beaver-like tail, and eats small freshwater animals at night such as shrimp, insects, frogs, and fish eggs. The platypus is endangered due to habitat destruction, overhunting for its fur, and pollution of its streams and rivers. Efforts to help the platypus include protection under CITES, education programs, and scientific study.
Reptiles and amphibians
Reptiles and amphibians are vertebrates that have a backbone. They can live on land, in water, or both. While reptiles breathe with lungs and have scales, amphibians breathe with gills as babies and lungs as adults and have soft, moist skin. Both reptiles and amphibians are oviparous, meaning they lay eggs.

Curious mammals and birds
The document discusses various characteristics of mammals and birds, including that echidnas and platypuses are egg-laying mammals, bats are the only flying mammal, elephants are the largest land mammal, dolphins have flippers to swim, giraffes are the tallest mammal, and blue whales are the largest animal. It also notes that Iberian lynxes are an endangered mammal found in Sierra Morena, penguins are aquatic but not flying, sparrows have short beaks to eat seeds, eagles and vultures have hooked beaks, ostriches are the largest and fastest running bird, pelicans use their beaks as nets, and hummingbirds have long thin beaks to drink
The platypus
The platypus faces several limiting factors in its environment. [1] It has many predators that it must defend against, so it evolved to secrete venom from spurs on its hind limbs, making it one of the few venomous mammals. [2] As a mammal that lives in an aquatic environment, it developed physical adaptations like webbed feet, fur to stay dry and warm, and a bill to locate food underwater without sight or hearing. [3] These adaptations allow it to thrive despite the challenges of predators and living in the water.
5 S Platypus
This document provides facts about the duckbill platypus. It details that the platypus lays eggs, has a lifespan of up to 16 years in the wild, and 10-12 years in captivity. Their back legs are more powerful than their front legs. Baby platypuses are born without hair, with small legs and closed eyes, and stay in their mother's burrow for the first six weeks. The platypus lives in underground burrows near water, and eats small fish, worms and bugs both in and out of water. Their webbed feet help them swim fast, and their thick fur allows them to swim underwater. The platypus is found in Australia.
Amphibian Defense Notes
The document discusses several means of defense used by amphibians, including producing toxic chemicals from skin glands, mimicry of poisonous species, warning coloration, hiding behavior, rapid escape, urination when grasped, and emitting a distress call when captured. Specifically, it notes that frogs and toads can release bufotenin from parotoid glands or that newts produce the lethal toxin salamandrin.
Frogs
Frogs live both on land and in water. Female frogs lay eggs in water, which hatch into tadpoles. Tadpoles live in water, breathing with gills and eating plants. Over time, the tadpole grows legs and lungs and its tail shortens until it transforms into a small froglet. The froglet is the final stage before becoming an adult frog without a tail.
Frog presentation
Frogs are amphibians that are cold-blooded vertebrates known for their distinctive ribbit call. They have scale-less skin, webbed feet, and live in a variety of habitats around the world. Frogs go through distinct life cycle stages from egg to tadpole to adult frog. They have over 3,000 different species that vary widely in size, coloration, diet and habitat, such as poison dart frogs, Goliath frogs, and wood frogs.

The Pacific sea nettle (Chrysaora fuscescens) lives in the Pacific and Indian Oceans. It feeds on zooplankton, small fish, crustaceans, and sometimes other jellyfish. The sea nettle jellyfish is round and orange in color, with long thin tentacles and some ruffled tentacles. They reproduce by releasing eggs into the water and do not have complex organ systems like a brain or nervous system. Myths from Japan explain why jellyfish do not have shells.
Samantha v frogs
Frogs are small, vertebrate animals that come in various sizes and colors. They have webbed feet and two eyes to help them jump and move through trees or water to escape predators. Small frogs mainly eat insects, spiders, and worms while larger frogs may eat rats, bats, and other small animals. Frog eggs hatch within 3-25 days and then the frogs continue growing through their life cycle.

The document discusses the five main groups of vertebrates: mammals, birds, amphibians, reptiles, and fish. It provides additional details about mammals, noting that they are viviparous, give birth to live young that feed on milk from their mothers' breasts. It specifies that whales, dolphins, and sharks are examples of marine mammals that live in water but breathe air through lungs. The document also mentions that birds breathe through lungs and lay eggs from which their offspring hatch, while fish breathe through gills and live exclusively in water, either freshwater or saltwater.
Why are fish fish-shaped?
Lauren Sallan explains that most fish have evolved streamlined bodies and fins that allow for efficient swimming. Flying fish can glide long distances while sailfish can swim over 100 km/hr due to bodies adapted for undulating movement powered by the tail and fins. Studying fish biomechanics through flow tanks and models provides insights into diverse swimming modes and how evolution has optimized fish shapes for aquatic locomotion over 500 million years.
Diferent animals inside the sea
The document discusses several types of sea mammals, fish, and invertebrates. It provides details on the bottlenose dolphin, blue whale, and sperm whale, describing their physical features, habitats, behaviors, and diets. It also profiles various fish species like the Atlantic cod, whale shark, and basking shark, as well as invertebrates such as Chinese mitten crabs, European green crabs, sponges, and starfish. Overall, the document aims to educate the reader about the diversity of marine life.
Subphylum Uniramia Notes
The document discusses the subphylum Uniramia, which includes classes of centipedes, millipedes, and insects. Centipedes have one pair of poison claws and use venom to catch prey, while millipedes do not have poison claws and scavenge plant materials. Insects have been very successful due to facing little competition or predation when they first evolved, having an exoskeleton for mobility, and an abundance of plant food sources. The major insect orders discussed are Coleoptera, Diptera, Hymenoptera, Isoptera, and Lepidoptera.
Animals bere and vicky
This document categorizes animals as either vertebrates or invertebrates. Vertebrates include animals like lions, fish, snakes, crocodiles, tigers, turtles and kangaroos that have backbones. Invertebrates lack backbones and include animals such as butterflies, snails, spiders, starfish, octopuses, ants and jellyfish. The document then provides examples of vertebrate and invertebrate animals categorized by their major subgroup.
The otter
Otters are semi-aquatic mammals that are usually found within a few hundred meters of water and depend on aquatic habitats for food. They have an almost worldwide distribution and feed on seafood, fish, and various invertebrates. Otters have a large, dark body with short, robust limbs and interdigital membranes, as well as a long neck, discreet eyes and ears, and abundant beards.
Coffee
The document discusses the global coffee industry, including that Brazil is the top coffee producer while Finland leads in consumption. It notes that while most consumption occurs in wealthy nations, production relies on small farmers in developing countries, who often suffer from low wages, poor conditions, and even slave or child labor. The coffee crisis has severely impacted the livelihoods of millions in developing nations dependent on coffee production.
Anthony crasto histrionicotoxin
Histrionicotoxin is a poison found in the skin of Dendrobates histrionicus, a type of poison dart frog found in South America. In the 1800s, tribes in Colombia and other parts of South America extracted the poison from these frogs and coated their hunting arrows and blow darts with it. The poison acts as a nicotinic acetylcholine receptor antagonist, paralyzing prey. Since the frogs were first reported on by a British explorer in 1823, scientists have studied histrionicotoxin's chemical structure and properties, as well as developing synthetic versions of the toxin.

Box jellyfish toxicity
Box jellyfish contain a potent venom that has caused over 5,000 deaths in Australia. Their venom attacks the heart, nervous system and skin cells, and a sting can cause death within minutes from cardiac arrest. Box jellyfish have 24 eyes, 15-foot long tentacles containing millions of venom capsules that can fire upon contact with chemicals on surfaces. Their venom is so toxic that 1 microgram per kilogram of body weight can be lethal in humans.
Poison dart frog
Poison dart frogs are small, brightly colored frogs found in Central and South America and Hawaii. They obtain potent alkaloid toxins from ants, mites, and other arthropod prey that provide chemical defense against predators. The golden poison frog contains the most lethal toxin called batrachotoxin, which in small doses of only 20 micrograms can kill 10-20 humans. While captive frogs do not develop toxins without an ant/mite diet, wild frogs can also obtain toxins directly from mites like Schloribates that produce their own alkaloids. Bacteria on the frog's skin may also contribute to their toxicity and disease resistance. Some of their potent toxins like epibatidine show promise as
Poison dart frog
Poison dart frogs live in tropical jungles in Central and South America. They are small, brightly colored frogs that secrete powerful toxins through their skin, which they obtain from ants, centipedes, and mites in their diet. These toxins can kill predators but one snake, the Leimadophis epinephelus, has developed immunity. Poison dart frogs play important roles in the ecosystem by controlling ant and mite populations and protecting plants from insects, but they face threats from deforestation and illegal trafficking.

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.

Dolphins evolved from land mammals and still retain some characteristics of land animals today such as fingers on their fins, nursing their young, and the ability to breathe air. They have highly developed hearing and communication skills. A curious fact is that dolphins can sleep with half their brain at a time, keeping one eye open for threats while resting the other half. They form groups of up to hundreds and have excellent hearing and group behavior.
11.08__Mollusks.pdf
Mollusks are a diverse phylum of invertebrates that live in both aquatic and terrestrial habitats. They have a hard outer shell, a mantle that secretes the shell, and a radula for feeding. The three main classes of mollusks are gastropods, bivalves, and cephalopods. Gastropods crawl on a foot, bivalves are sessile filter feeders attached to surfaces, and cephalopods are active carnivorous swimmers with arms and tentacles.
Vertebrates
- Most fish breathe through gills and have skeletons made of bone or cartilage. They propel themselves through water using tail fins and other fins. Fish come in a wide variety of sizes, from less than an inch to over 60 feet long.
- Reptiles are air-breathing vertebrates covered in scales that lay eggs. Examples are crocodiles, lizards, snakes, turtles, and tortoises. They are often cold-blooded and regulate temperature behaviorally.
- Birds are feathered flying animals with wings, beaks, and lightweight skeletons adapted for flight. Their respiratory and skeletal systems are specialized for flying.
animalkingdom
The document classifies and describes different types of animals. It divides animals into invertebrates, which lack backbones, and vertebrates, which have backbones. Invertebrates include protozoa, annelids, arthropods like insects and crustaceans, echinoderms, and mollusks. Vertebrates include fish, amphibians, reptiles, birds, mammals, and primates like humans. Within these groups it describes characteristics of common animals such as starfish, earthworms, spiders, whales, and mice.
Amphibians
Amphibians are vertebrates that spend part of their life in water and part on land. They evolved from lobe-finned fish around 350 million years ago. Amphibians have adaptations for both aquatic and terrestrial environments like the ability to hibernate, estivate, and lay eggs in water that hatch into larvae. Common types of amphibians include frogs with short bodies and long back legs for jumping, toads with thick warty skin that live on land, and salamanders with slender bodies that hide under debris.
Amphibians
Amphibians begin their lives in water, living as larvae that use gills to breathe. They undergo metamorphosis to transition to life on land as adults, developing lungs and three-chambered hearts. Most amphibians return to water only to reproduce and lay eggs that hatch into larvae, leading double lives both on land and in water. The two main groups are salamanders and frogs/toads.
Amphibians
Amphibians are tetrapods that either live on both land and water or have different life stages in each habitat. There are three modern orders of amphibians:
1. Caudata (salamanders and newts): Found in cool, moist habitats in the Northern Hemisphere. They have moist skin and internal fertilization. Larvae develop in water.
2. Gymnophiona (caecilians): Worm-like amphibians found in tropical regions. They burrow underground and have either aquatic or terrestrial larvae.
3. Anura (frogs and toads): Found worldwide in moist habitats. They undergo metamorphosis from aquatic tadpoles to terrestrial

Amphibians
Amphibians are vertebrates that live in water as larvae and on land as adults. They have moist skin without scales or claws. There are three types of amphibians: salamanders, frogs and toads, and caecilians. Amphibians evolved to live partially on land by developing stronger bones, lungs, and breathing tubes. They can breathe through their skin but some live on land for more available food. Amphibians have external fertilization and undergo metamorphosis from embryo to adult. Frogs jump while toads prefer land. Salamanders and newts have different skin textures. Axolotls never develop lungs while caecilians resemble worms and live underground.
Sea Creatures
The Dumbo Octopus is one of the rarest species of octopus that lives in deep ocean waters. It moves through jet propulsion and uses its eight arms and elephant-ear-like flaps. Dumbo Octopuses eat small animals whole and can dive deeper than any other octopus, as far as 7,000 meters below sea level.

Science fungi p.point
The document discusses the classification of fungi in the kingdom, describing how they are classified based on their structure and reproduction methods. It identifies some common types of fungi, including molds, zygomycetes, sac fungi known for their reproductive sacs, club fungi named for their club-shaped reproductive structures, and imperfect fungi whose reproductive phases are not observable. It provides links to additional information and sources.
Amazing Sperm Plants
Flowering plants first appeared around 135 million years ago and have since diversified greatly. They have flowers that attract pollinators like bees, helping the plants reproduce. There are over 500 ways to classify flowers based on their many variations from crossed genes between species. Angiosperms can be divided into two main classes - monocots and dicots - based on their seeds and seedling structure. Monocots have one seed and dicots have two. Angiosperms can also be classified as woody, herbaceous, annual, perennial, or biennial based on characteristics like their stem structure and lifespan.
Cnidarians
Cnidarians are a phylum of aquatic animals that include jellyfish, corals, sea anemones and hydroids. They live in oceans around the world, from the surface waters to the deep sea. Cnidarians have two life stages - a free-swimming medusa stage and a stationary polyp stage, where they are attached to a surface. Their life cycle often involves both a medusa and polyp form.
Stems
Stems perform several functions like producing leaves, branches, and flowers. They transport substances between roots and leaves and hold leaves up towards sunlight. Monocots have vascular bundles arranged in the stem, while dicots and gymnosperms have vascular bundles arranged in cylinders with xylem and phloem tissue. Primary growth occurs through cell division at the stem tip in all seed plants, resulting in increased length. Secondary growth occurs through thickness, with cork cambium forming the outer covering and vascular cambium between vascular tissues producing new layers of xylem wood.
Gretchen Harrigan
Fungi are living organisms that are more closely related to animals than plants. They absorb nutrients from decaying matter in the soil rather than producing their own food through photosynthesis. Fungi are made up of fine threads called hyphae that intertwine to form a tangled web-like structure called a mycelium. Hyphae may contain cross walls that divide them into separate cells. Fungi play an essential role in the environment by aiding plant root function and breaking down dead organic material.
Chordates
Seedless vascular plants reproduce without seeds and have structures that transport water and nutrients throughout the plant. They include club mosses, horsetails and ferns, which have roots, leaves and stems. The dominant stage in a fern's life cycle is the sporophyte, which is diploid.
Leaves, Roots, And Stems
Sponges are multicellular animals that live attached to surfaces in marine environments. They filter feed by drawing water through their bodies to absorb nutrients while releasing waste. Sponges can reproduce both sexually through internal fertilization or asexually. There are over 5,000 known sponge species. Sponges were some of the earliest forms of animal life on Earth.
This Is My Power Point
Leaves are the main organs for photosynthesis in plants. They are made up of a thin flattened blade connected by a petiole stalk to the stem. The blade is covered by an epidermis layer and vascular tissues which transport water and nutrients. Mesophyll tissue inside the leaf contains chloroplasts that perform photosynthesis, producing carbohydrates that move through phloem vessels to the rest of the plant. Sunlight is absorbed by palisade mesophyll cells at the top and travels through spongy mesophyll cells at the bottom. Stomata pores allow gases like oxygen and carbon dioxide to diffuse in and out for photosynthesis. Water lost through transpiration is replaced through xylem vessels in the vascular tissue
Powerpoint
Archaebacteria differ from eubacteria in that they lack peptidoglycan and have distinct membrane lipids, and their DNA sequences are more similar to eukaryotes. Archaebacteria thrive in harsh environments like digestive tracts, salty lakes, and oxygen-depleted mud. Prokaryotes use flagella for movement and undergo cellular respiration for energy. They can also exchange genes between cells through conjugation. Prokaryotes reproduce through binary fission, doubling in size before dividing into two daughter cells.
Kyle Wood
1) Different types of algae, called protists, are described including euglenophytes, dinoflagellates, and chrysophytes.
2) Euglenophytes are plantlike protists that reproduce through binary fission and have two flagella but no cell wall.
3) Dinoflagellates can be photosynthetic or heterotrophic, reproduce through binary fission, and store DNA but not histones like other organisms.
Mammals
Mammals are classified into several groups based on how their young develop. Marsupials carry their young in pouches after they are born. Monotremes lay eggs that hatch outside the body. Placental mammals exchange nutrients between the mother and embryo through the placenta. There are many types of placental mammals including those that live on land or in water, fly, have hooves or trunks. Convergent evolution has led to similar structures developing in different mammals living in similar climates.
Fishes
This document discusses the characteristics, evolution, feeding, and respiration of fish. It notes that fish generally have paired fins, scales, and gills. Originally fish were armored and jawless, but in the Devonian Period fish evolved paired fins and jaws. Fish can feed in different ways depending on their environment, including herbivores, carnivores, parasites, filter feeders, and detritus feeders. Gas exchange occurs through gill filaments and blood circulates through fish in one loop.
Primates And Human Origins Powerpoint
The document discusses primates and human origins. It defines hominids and primates, noting that hominids evolved to walk upright and have opposable thumbs, while primates have binocular vision and well-developed brains and limbs. It outlines the two hypotheses for modern human evolution - the multi-regional model suggesting independent evolution in several places, and the out-of-Africa model where Homo sapiens first evolved in Africa from earlier species like Homo habilis, Homo ergaster, and Homo erectus. It also discusses Homo neanderthalensis and evidence that Homo sapiens lived alongside them around 50,000-40,000 years ago.
Viruses Final Presentation!
There are three main types of bryophytes: mosses, which commonly grow in moist areas; liverworts, which resemble flat leaves attached to the ground and get their name from resembling a liver; and hornworts, which are found in soil damp year-round. Bryophytes are non-vascular plants that are typically found in damp, moist environments like evergreen forests and go through a life cycle of growth, reproduction, and dispersal.

Viruses are particles that can only reproduce by infecting living cells and contain nucleic acid, protein, and sometimes lipids. They do not have fossils but may have impacted life's history. Viruses use capsids made of protein to enter host cells. Some viruses infect bacteria while others contain RNA as their genetic material or are made solely of protein. Viral infections can be lytic, causing the cell to burst, or lysogenic where the virus embeds its DNA into the host cell DNA. Many human diseases are caused by viruses such as polio, measles, AIDS, influenza, and rabies.

Ecology Of Fungi
Fungi are heterotrophs that obtain nutrients by breaking down and absorbing organic matter using digestive enzymes and thread-like mycelium. As decomposers, fungi recycle nutrients by breaking down dead organisms and waste. Some fungi are also parasites that can cause diseases in plants, animals, and humans. Fungi also form symbiotic relationships with photosynthetic organisms like lichens and plant roots through mycorrhizae.

Birds have wings and feathers that allow them to fly. They maintain a constant internal body temperature and have specialized features like bills and digestive systems that help them survive. There are many groups of birds including songbirds, raptors, and flightless birds. Birds play important ecological roles like seed dispersal and pest control. They have been around for over 150 million years.
Reptiles Sigrid Ryan
Reptiles are scaly animals that live in warm areas and eat plants or small animals. There are several types of reptiles including lizards, snakes, crocodilians, turtles, and tortoises. Reptiles are ectothermic, meaning they rely on external heat sources like sunlight to regulate their body temperature. While dinosaurs were the largest reptiles to ever live, modern reptiles have diversified to fill ecological niches through evolution from a common ancestor.
