hello there!!!
Ambhibians , lizard have 3 chambered heart , 2 atria and 1 ventricle...
ambhibians and reptiles are cold blooded animals.
Ambhibians ----> These animals are different from fish because they lack scales that fish have..........
Respiration is through either gills or lungs .. these animals lay eggs..
they are found both in the water and on land... E.g:- frogs , toads and salamander......
Reptiles-----> These animals have scales and breathe through lungs , while most of the animals have a three chambered heart except crocodiles .... crodiles have four chambered heart .... they lay eggs with tough covering and don't need to lay eggs in the water unlike amphibians....
