Turtles are reptiles rather than amphibians based on three key characteristics: they have shields covering their skin rather than smooth skin; their toes have claws; and their eggs have thick, hard shells, unlike the permeable eggs of amphibians. Amphibians have permeable skin and lay eggs without hard shells, while reptiles are covered in scales or plates and have claws, with eggs that have thick shells.

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.
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.
Amphibians 10-8 miryana bedros yuliya
Amphibians are a class of vertebrate animals that live both on land and in water. They have moist skin, four limbs, undergo metamorphosis from an aquatic larval stage to a terrestrial adult stage, and include frogs, salamanders and caecilians. The largest orders are Anura (frogs), Urodela (salamanders), and Gymnophiona (legless caecilians). Amphibians play an important role in ecosystems and some species are used in medical research.
Amphibians karina siyana_10.7
Amphibians live both on land and in water. They undergo metamorphosis from egg to aquatic larvae to adult with lungs and limbs. Amphibians reproduce sexually by laying eggs in moist environments that develop into larvae with gills. Common UK amphibians include toads, frogs, and newts that live near water and eat insects, worms and other invertebrates.
12 3 Amphibians
Amphibians such as frogs, toads, and salamanders spend their early life in water and their adult life on land. They have adaptations like camouflage, legs, and lungs that allow them to live on both land and water. However, amphibians are sensitive to environmental changes and facing threats due to habitat loss, pollution, and other factors.
Amphibians
This document provides an overview of amphibians including their characteristics, evolution, examples of different types of amphibians like frogs, salamanders, and caecilians. It discusses their anatomy, life cycles, habitats, defenses, diets, and more. Amphibians are defined as animals that develop outside the body, have glandular skin without scales, and can breathe through gills or lungs. They first appeared around 340-270 million years ago.
Invertebrate examples
The document describes several marine invertebrate species, including the giant Japanese spider crab, bat sea star, giant African millipede, California sea cucumber, giant Pacific octopus, coral banded shrimp, cuttlefish, European medicinal leech, brown rock urchin, giant green anemone, oyster, and tube sponges. For each species, it provides the scientific name and some key details about physical characteristics, behaviors, life cycles, predators, and other biological or ecological information.
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.

- Penguins that are birds that cannot fly, live in polar regions, and eat small fish.
- Cats that are carnivorous pets living in homes and hunting small animals.
Amphibians
Amphibians evolved from lobe-finned fishes around 345 million years ago. They can live both on land and in water, using various organs for respiration in different environments. There are over 2,000 living amphibian species classified into four orders: Anura (frogs and toads), Urodela (salamanders), Trachystoma (mud eels), and Apoda (caecilians). Amphibians have key adaptations like permeable skin and an aquatic larval stage that allow them to transition between aquatic and terrestrial habitats.
Frogs by Rocío
Frogs belong to the amphibian group and lay their eggs in water, where baby frogs live and grow while breathing through gills. Adults frogs breathe through lungs and skin and eat small animals like mice and worms, using webbed feet to swim and strong back legs to jump. The poison dart frog is particularly beautiful with a long, sticky tongue.
Invertebrate examples
The document describes 14 different marine species, providing 1-2 paragraphs on each species that includes its scientific name, key identifying characteristics, behaviors, and other notes.

This document provides information about the life cycles and habitats of amphibians that live in Ohio. It explains that amphibians have a two-part life cycle where they live in water as tadpoles and then on land as adults. Common Ohio amphibians include 14-15 species of frogs and toads across 4 families. The document also describes the differences between frogs and toads, what frogs eat, how long they live, and includes activities about identifying local amphibians and measuring how far a frog can jump.
ARACHNIDS AND MYRIAPODS
Arachnids and myriapods are classes of arthropods. Arachnids include spiders, ticks, mites and scorpions and have 4 pairs of legs, pedipalps near the mouth, and chelicerae fangs. They reproduce through a male transferring sperm in a package to the female. Myriapods include millipedes, centipedes and have a range of legs from over 750 to under ten. They live in forests, mountains and moist places and eat insects or detritus depending on the species.

This lesson is all about amphibians. This lesson also covers how amphibians are classified into 3 groups: Anura, Caudata, & Gymnophiona. Also, this lesson concludes with the roles amphibians play in our ecosystems, ways we can help, population declination, with a summary to wrap it up.
Froggys
Amphibians like frogs and toads are some of the earliest living vertebrates that evolved during the Devonian period. Many amphibian types went extinct over time, but those still living today include frogs, toads, salamanders and newts. Frogs are commonly used in laboratories to study anatomy, behavior and evolution. Their reproduction involves external fertilization of jelly-like eggs. As tadpoles, they have tails and gills but later develop lungs and legs to live on land as adults. Frogs play an important role as predators in the food chain, eating insects.
Darwin and lamarck evolution theories
Lamarck and Darwin proposed theories to explain the evolution of giraffe necks. Lamarck's theory was that giraffe ancestors continually stretched their short necks to reach higher leaves, causing their necks to gradually grow longer over generations. Darwin's theory was that both short and long-necked giraffes originally existed together, but as trees grew taller, short-necked giraffes starved since they could not reach leaves, while long-necked giraffes survived and passed on their long necks.
Herpetology
Herpetology is the study of reptiles and amphibians. It is an important field that provides insights into conservation, medical research, and environmental quality. Amphibians are especially useful as bioindicators because they absorb water and chemicals through their skin. Many amphibian species are threatened or endangered due to habitat loss, disease, pollution, and other factors. Reptiles and amphibians display a wide variety of adaptations for living on land or in water, and fulfilling different ecological roles in ecosystems.

Auto wired dependency injection in js
Attending this session would allow the audience to:-
1) understand dependency injection as an IoC technique
2) appreciate its merits and its essentiality in building scalable web applications
3) spot and identify dependency injection in the wild
4) understand how we could achieve autowiring in JS (a la Spring in Java)
Authoring a webapp for scalability is not easy. There are a lot of parameters to keep in mind as the design takes shape. Some of these are quite fundamental in nature and yet often overlooked:-
(1) Separation of concerns
(2) Single responsibility principle
(3) testability
In this session, we shall look at employing Dependency Injection as a technique to help improve our code (especially w.r.t. testability).
We then briefly look at some of the existing techniques that achieve D.I. (to some extent).
Next, we look at how an auto-wiring DI implementation can help improve the code (taking the example of a simple application).
Finally, we showcase how this is currently implemented using WinterJS.

MeetTheMammalsSlidesAndNotes.pdf
The platypus uses its sensitive snout to detect tiny movements of prey in rivers and streams, as its skin covers its eyes and ears when it dives. It is one of few mammals that lays eggs. Wallabies are marsupials where tiny babies live in their mother's pouch to feed and grow until around 10 months old. Dolphins are powerful swimmers that can reach speeds over 20 mph with their streamlined shape, strong tail flukes, and steering flippers, though they usually swim at 5 mph. Bats have built-in radar called echolocation that helps them fly and hunt in darkness by emitting high-pitched noises.
Amphibians
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.
Major groups of animals
The document classifies animals into two major groups: invertebrates and vertebrates. Invertebrates lack a backbone and include soft-bodied animals like sponges, jellyfish, worms, insects, mollusks and arthropods. Vertebrates have backbones and include fish, amphibians, reptiles, birds and mammals. The document provides examples of different types of animals from each major group and their distinguishing characteristics.
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.
Animal kingdomasisixb-1218460538141865-9
This document provides an overview of animal classification by discussing invertebrates and vertebrates. It notes that over 98% of animal species are invertebrates, which lack backbones, while vertebrates have backbones. Common invertebrate groups include protozoa, annelids, mollusks, echinoderms, crustaceans, arachnids, and insects. Vertebrate groups include fish, amphibians, reptiles, birds, and mammals such as marsupials, primates, rodents, whales, dolphins, and seals. Each group is briefly characterized.
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
3rdGradeReptilesandAmphibians.ppt
There are over 6,800 reptile species including alligators and crocodiles, turtles and tortoises, snakes, and lizards. Reptiles are ectothermic vertebrates with scaly skin and internal skeletons. They lay shelled eggs and undergo little development from hatching to adulthood. Amphibians include over 4,000 species of frogs, salamanders and caecilians. They are also ectothermic vertebrates but have permeable skin and undergo metamorphosis from aquatic young to terrestrial adults. Both groups shed their skin and use environmental heat to regulate their body temperature.
Classification of Animals-Seanna Sofiah Santillan.ppt
This document classifies and describes the characteristics of vertebrates and invertebrates. Vertebrates include mammals, birds, reptiles, amphibians, and fish. They are defined as animals with backbones. Invertebrates make up 97% of animal species and do not have backbones. They are grouped into sponges, jellyfish, worms, mollusks, arthropods, and starfish/sea urchins. Each group has distinguishing traits such as exoskeletons, segmentation, or shells.
Reptiles
This document provides information about reptile movement, diet, reproduction, anatomy, and adaptations. It discusses how different reptiles like lizards, turtles, alligators, and crocodiles move in various ways depending on their environment. It also addresses what reptiles eat, how they reproduce, their general body structure including skin, heart, lungs, and temperature regulation. The document seeks to educate about reptiles and answer reader questions on their role in the food chain, history, adaptations, and unique species.
Vertebrates
Vertebrates can be classified into five categories: birds, fishes, amphibians, reptiles, and mammals. Birds are warm-blooded creatures that lay eggs and have feathers and wings to fly. Fishes live in water and have fins and gills. Amphibians live both on land and in water, starting as eggs with gills. Reptiles are covered in dry scales, some lay eggs while others give live birth. Mammals are warm-blooded, have hair or fur, and most give live birth.

The document discusses different groups of animals including amphibians, birds, mammals, reptiles, and insects. It provides 3 key characteristics for each group:
Amphibians are vertebrates that are ectothermic, breathe through their skin, and go through metamorphosis. Birds are vertebrates that are endothermic, have feathers, and lay eggs. Mammals are vertebrates that are endothermic, have hair, and produce milk to feed their young. Reptiles are vertebrates that are ectothermic, covered in scales, and have lungs. Insects are invertebrates that have a 3-part body structure, hatch from eggs, and have 6 legs
Animals That Lay Eggs (with Pictures).pdf
Organisms have different methods of reproduction. To tell the truth, these different reproductive methods are the factors that divide animals into two categories: viviparous and oviparous animals. But more on that in a bit, here's a blog on the many different animals that lay eggs!

Nature's way of maintaining the ecological balance on earth is something special. For example, Mother Nature has endowed living animals with the ability to go through the process of labor to directly give birth to their own kind.
Whereas, oviparous animals lay eggs that give birth to young as soon as they hatch.
Now, if you are stuck wondering because nature has allocated different reproductive processes to different animals, then we are just as clueless as you!
However, you can acknowledge the fact that every process created by nature is purposeful. For example, if nature has given birds the ability to lay eggs to produce their offspring, it may be for their own benefit.
The main reason for this is that birds cannot fly while carrying the weight of their young. By laying their eggs in a remote location, they thereby safeguard both themselves and their offspring.
We also understand how interested you are in learning about the ovoid animal species.
So, read on to know more about the complex egg-laying process and a description of the top 13 animals that lay eggs.
Animals That Lay Eggs
If we were to list all oviparous animals, you would get tired of reading the never-ending list!
A large number of prominent species in the animal kingdom are oviparous, including insects, birds, amphibians, reptiles, fish and even some mammals.
So, if you are ready to know about 13 animals that lay eggs, connect with us!
Birds
Birds are the first members of our list of animals that lay eggs. Birds are the most lively and colorful species of the animal kingdom, somewhat related to the ancient family of reptiles, the dinosaurs.
They are a very unique creation of nature because they are the only animals with feathers that are known to exist on Earth. These warm-blooded vertebrates are also known to be closest to reptiles due to the rough shape of their feet.
The largest birds alive today are the North African ostriches, which can reach 9 feet in height and weigh up to 350 pounds. The ostrich egg is the largest of any other bird species.
On the other hand, the smallest extant birds are Cuban native hummingbirds weighing less than 3 grams.
Also, the bird's feathers make them stand out among every other species.
However, having wings does not guarantee a bird's ability to fly. There are several flightless birds, including penguins, kiwis and ostriches, which, although they have wings, cannot fly due to some evolution that took place over the years.
Also, bird eggs have a hard shell that ensures safety and are laid in secluded areas like bird nests, such as a treetop or an abandoned room. The parents fulfill the responsibility of taking care it...
Invertebrates and vertebrates
The document discusses the classification of animals into two main groups - vertebrates and invertebrates. It provides details about the key characteristics of each group and some examples of animals that belong to each. Invertebrates are defined as animals without backbones, and include sponges, worms, mollusks, arthropods, echinoderms, and protozoa. Vertebrates have backbones and include fish, amphibians, reptiles, birds, and mammals. The document then goes into further detail about some examples of invertebrates and vertebrates.
Classificationofanimals
This document provides a classification of animals, dividing them into vertebrates and invertebrates. Vertebrates include mammals, fish, reptiles, birds and amphibians, which are further defined by their key characteristics such as how they reproduce, regulate body temperature, breathe and move. Invertebrates make up 97% of the animal kingdom and lack backbones, including sponges, corals, jellyfish, worms, starfish, mollusks, arthropods and insects. They are grouped according to their physical traits and structures.
Eyewitness reptile
This document provides an overview of reptile anatomy and physiology. It describes how reptiles first evolved over 300 million years ago and were the dominant land animals for much of the Mesozoic era. Today there are only four major groups of reptiles: snakes, lizards, crocodilians, and turtles. The document discusses reptile skin, senses, reproduction, growth patterns, and other internal and external features. It also provides examples of different reptile species to illustrate these characteristics.
Sea wasp
The Box jellyfish lives in northern Australia and New Guinea, found both deep in the ocean and near coral reefs. It is a skilled hunter with 24 eyes that help it hunt, though only 16 can detect light. Most have a clear body with white stingers, and a box-shaped bell rather than a dome. Their conservation status is unknown but their population is likely in the millions. They feed on small fish and zooplankton. Reproduction occurs when male jellyfish release sperm into the water that fertilizes eggs on the female's tentacles. Box jellyfish are predators in their ecosystem and few predators can withstand their venom.
Classification of animals
This document classifies and describes the key characteristics of vertebrates and invertebrates. Vertebrates include mammals, fish, reptiles, birds and amphibians, and can be found around the world. They are divided into groups based on traits like whether they lay eggs, have feathers or fur, breathe through lungs or gills, and how they regulate their body temperature. Invertebrates make up 97% of animal species and lack backbones, including insects, worms, sponges, jellyfish, starfish, mollusks and arthropods. They are grouped by their exoskeleton, body structure and environment.
different reptiles in oriya laguage.pdf
Reptiles are defined as vertebrate animals with dry scaly skin that lay soft-shelled eggs on land, including snakes, lizards, turtles, and tortoises. They have changed little from their first appearance over 200 million years ago. Turtles have a protective shell covering their body that provides camouflage and is composed of two parts. The earliest known proto-reptiles originated around 312 million years ago and evolved from tetrapods adapted to life on dry land. Reptiles produce amniotic eggs with membranes and shells that help prevent drying out and allowed them to be the first vertebrates to adapt to life on land.
FreshWater Turtles
Freshwater turtles have shells that protect their bodies and come in many shapes and sizes. Some turtle species are endangered. Turtles have claws and webbed feet to help them swim. They breathe air and live both on land and in water. Female turtles choose their mates and lay eggs without help from males. The largest freshwater turtle is the alligator snapping turtle and the smallest is the bog turtle. Some turtles make interesting pets.
FreshWater Turtles
Freshwater turtles have shells made of bone or cartilage that act as shields for protection. They come in many shapes and sizes, and some species are endangered. Female turtles choose their mates and are responsible for egg-laying, while males compete for mates and provide fertilization. Examples of notable freshwater turtles include the largest, the alligator snapping turtle, and the smallest, the bog turtle. Some freshwater turtles are also kept as pets, with the red-eared slider being most common.

Amphibians and Reptiles
- 2. Are TurtlesAmphibians or Reptiles?
- 3. Let’s examine the characteristics of each category: Amphibians Amphibians have smooth, scaleless skin which is permeable to water. The eggs of amphibians lack a hard outer covering and, thus, must be laid in water or in damp places1 1 "The Animal World - What Is The Difference Between A Reptile And An Amphibian?." Science Fact Finder. Ed. PhillisEngelbert. UXL-Gale, 1998. eNotes.com.
- 4. Reptiles Reptiles are covered with scales, shields, or plates, and their toes have claws. The eggs of reptiles have a thick, hard shell that protects the developing embryo from moisture loss, even on dry land.2 2"The Animal World - What Is The Difference Between A Reptile And An Amphibian?."
