Compared to some areas of the tropics this is a paltry number: Colombia, for instance, has 754 amphibian species, with ten new species found just this year.
But Idaho still has some interesting frogs, toads and salamanders that you might see. Some, like the tiger salamander (above), may very well be in your backyard.
The Idaho giant salamander (above) prefers forest habitat. It often hides under logs, and is known for its tendency to "growl" when threatened. The Columbia spotted frog is a desert species; look for it in wetlands and low flowing rivers of the Owyhees.
