Since the 1980's herpatologists have noted an alarming decline worldwide in populations of amphibians. Habitat destruction and climate change have been suggested as possible causes, but one thing that can be pointed to with certainy is the fungal disease Chytridiomycosis.

A mysterious outbreak of fungal disease has wiped out an estimated 170 species in the past decade, and put more than one-third of the world's remaining amphibians at risk.

A group called Amphibian Ark is calling on zoos and aquariums to join in the conservation efforts and become sanctuaries for these species while they disappear from the wild.

By the way, how many kinds of blue animals (besides frogs) can you think of?

fish
butterflies, and other bugs
birds
(I don't think blue whales count)
