History
There are perhaps 3,500 different species of frog alive today, on all continents but Antarctica, making frogs the most numerous amphibian. The word amphibian, incidentally, means double life, which refers to frogs living part of their lives in water and part on land. Frog-like fossils have been found in Triassic era rocks, which means frogs observed the complete rise and fall of dinosaurs and yet still exist today.
