Amphibians

AMPHIBIANS




Amphibians (frogs, toads, salamanders, newts, and caecilians) are cold-blooded (ectothermic) vertebrate animals that lay eggs in the water and the young are water-breathing until they reach adulthood and become air-breathing. Most amphibians have four limbs, although caecilians typically have none.

Amphibians serve as valuable indicators of ecological declines (much like a canary in a coal mine) and the recent amphibian crisis indicates that there has been a dramatic decline in amphibian populations around the globe due to factors such as infectious diseases and man-made influences such as habitat encroachment, pollution, and climate disruption.
