Although amphibians and reptiles are cold-blooded vertebrates that look similar on the surface, there are some things that set them apart.
Amphibians lay their eggs in water, and most change from water-breathing juveniles to air-breathing adults. Frogs, toads, salamanders, newts and mudpuppies are all amphibians.
Reptiles are “amniotes.” This means that most, like birds and some mammals, lay shell-encased eggs on land and start life as air-breathing juveniles. Snakes and turtles are reptiles.
