amphibians literally live a double life (Greek amphibios) and were the earliest tetrapods (four-legged animal) to adapt to a terrestrial existence
frogs and toads are tailless; salamanders and newts have tails (blind worms/ caecilians are strange creatures found only in the tropics)
the special naked skin (no hair, feathers, scales) of amphibians
amphibians rarely drink water, unless it comes with their food
The main color and markings of an amphibian's skin are produced by three different pigment cells -- white, yellow, and brown-black.

in general, frogs are more active and like water more than toads -- and have webbed feet while toads have little or no webbing
most frogs have moist skin and live in or near water, while toads generally have dry, bumpy skin and live on land - and they have their own distinctive songs
