amphibians don't have legs
No, tortoises are reptiles. They are cold-blooded, have four legs, and lay amniotic eggs.
They are all vertebrates, and the reptiles and amphibians belong to the tetrapods because they have four legs.
Well there are many differences but the main one is that frogs have legs and snakes do not. Also frogs are amphibians and snakes are reptiles.
Well DUHH birds arn't like any of them because they are not that's why u gaywod and reptiles arn't like them because thay have no legs and amphibians are smelly and mammals give birth to live buttholes
All tetrapodes , mammals , birds , reptiles and amphibians .
It's an amphibian becuase...most reptiles cannot survive underwater and since it grows legs and lungs later on then yes it is an amphibion XD
Fish, and all invertebrates, as those have more than four legs or none at all. Only amphibians, reptiles, birds and mammals classify as tetrapods.
No, not in a straight forward traditional classification sense... Amphibians = class Amphibia Reptiles = class Reptilia Bird = class Aves Mammals = class Mammalia They can be categorized all together in the "superclass" Tetrapoda.
There is no real purpose of mammals. Fish grew legs, becoming amphibians which evolved into reptiles which eventually evolved into small rodents such as a mole or rat.
A bird's appendages are its legs, tail, and wings.
An amphibian is a cold blooded animal that breathes through aquatic gills. An insect is a small arthropod animal that has 6 legs and most have wings.
It depends on the type of reptile and amphibian. Frogs and toads usually have shorter front legs with webbed feet with longer back legs that have more paddle shaped feet that are webbed together. Lizards usually have regular sized front legs but have longer back legs. Geckos have feet with millions and millions of adhesive hair hooks for them to climb on almost anything. Salamanders and newts usually have stubby legs that have webbed toes since they rely mostly on their tail for swimming and walking. Snakes of course have no feet and turtles usually have stubby clawed feet. Hope this helped!!!
