Frogs are the most numerous of the world's amphibians, but they are rapidly declining, and many species are actually facing the imminent threat of extinction. "Pollution, global warming, and habitat destruction from human development have already taken a serious toll," reports Animal Planet. "Frogs, in particular, have suffered, having lost an estimated 170 species in the last 10 years alone." Frogs are also affected by a singular danger that is threatening their populations worldwide: the chytrid fungus, which coats frogs' skin and seals out vital moisture and kills frogs by dehydration.
