Synopsis

Amphibians—including frogs, toads, salamanders, newts, and the limbless caecilians—represent a fascinating group of creatures that bridge the divide between aquatic and terrestrial life. Characterized by their smooth, often moist skin, these animals are cold-blooded, meaning their internal temperature fluctuates with the surrounding environment. A defining feature of amphibian development is metamorphosis, a dramatic transformation from larval to adult form.
