What is common among amphibians?

Amphibians are small vertebrates that need water, or a moist environment, to survive. The species in this group include frogs, toads, salamanders, and newts. All can breathe and absorb water through their very thin skin. Amphibians also have special skin glands that produce useful proteins.

What is the difference amphibians and reptiles?

Amphibians are frogs, toads, newts and salamanders. Most amphibians have complex life cycles with time on land and in the water. Their skin must stay moist to absorb oxygen and therefore lacks scales. Reptiles are turtles, snakes, lizards, alligators and crocodiles.

What is the difference between a reptile and an amphibian?

What characteristics do both reptiles and amphibians share?

Both reptiles and amphibians have similar cloacal chamber which is an outlet where intestinal, urinary and genital tracts open. Both depend upon spinal segmental reflexes to control movement. Both have a three-chambered heart (crocodiles have four chambers) with two atria.

Similarities Between Amphibians and Reptiles Both amphibians and reptiles belong to the phylum chordate under the kingdom Animalia . Both amphibians and reptiles are ectothermic (cold-blooded) animals. Some amphibians and reptiles have four limbs. Both amphibians and reptiles have a heart with three chambers.
