Frogs | Salamanders
Amphibians are cold-blooded vertebrates with skin that lacks hair, feathers, or scales, and they breathe through both skin and lungs. The word "amphibian" comes from the Greek words "amphi" and "bios", meaning "double life" because amphibians can live on land as well as water. Most have a larval aquatic form and an adult terrestrial form. In general, amphibians need to be near water when they breed in order to lay eggs in or over water where the tadpoles can then hatch.
Amphibians can be divided into 3 groups:
- Frogs and Toads (Anura)
- Newts, Salamanders, and Sirens (Urodela)
- Caecilians (Gymnophiona)
We currently have frogs and salamanders in the BGSU Herpetarium.
Frogs have a distinctive body type: a large head that merges with a fat body, a wide mouth, large eyes, no tail, and back legs longer than the front to aid in jumping. They have highly permeable skin that secretes mucus to keep it moist. Most species utilize external fertilization.

Salamanders are tailed amphibians that have a narrow head with small eyes and a relatively small mouth. They have a body shape similar to lizards, but salamanders differentiate themselves with their permeable skin. All four legs of the salamander are approximately the same size, so they walk slowly to moderately fast.
While most salamanders can live on land, they reside in close proximity to water. Many salamanders are temperate or subtropical and require a moist habitat.
