Frogs and toads (order
Anura) are
tailless amphibians. They usually begin their lives in water
as tadpoles. While frogs and toads have the same basic
anatomy there are some general differences. Usually, frogs
have smooth, moist skin and long legs while toads have dry,
warty skin and short legs. Toads can live in drier areas.
Frogs and toads have excellent senses; while they cannot
turn their heads, they have very good peripheral vision.
Salamanders (order
Caudata) are
smooth-skinned, long-bodied, long-tailed amphibians that
have no claws or ear openings. They have two or four legs.
They require a damp environment because their skin, which is
slimy, does not protect them against moisture loss. They can
regenerate legs and tails and even retinas and optic nerves.
They are nocturnal and feed on a wide variety of insects.
