It's not just fish who rely on clean water to thrive, amphibians do too! An amphibian is any cold-blooded animal that has an aquatic, gill-breathing larval stage followed by a lung-breathing adult stage - like these POISON DART FROGS.
There are over 200 species of poison dart frogs that all inhabit the humid rainforests of Central and South America. Their brightly colored skin warns would-be predators that they are highly toxic. Look, don't bite! Poison dart frog eggs are laid on land, but when the tadpoles hatch, their parents will give them piggy-back rides into the nearest body of water.
