Tailed Frogs
Ascaphus
Tailed frogs are special frogs that have a little tail! They live in cool, clear streams and are great swimmers. These frogs are very unique because they can stay underwater for a long time.
Habitat: Mountain regions
Appearance
The Tailed Frogs are small, flattened amphibians with rough, bumpy skin, usually camouflaged in shades of brown, gray, or olive green. Males uniquely possess a short, tail-like cloacal extension for reproduction. They lack visible eardrums, setting them apart from most other frogs.

Interesting facts
Tailed frogs are considered living fossils, very ancient creatures.
Their "tail" is not for swimming; it's a special reproductive part!
These frogs can live longer than many pet cats or dogs!
They thrive only in extremely cold, pristine mountain streams.
Special abilities
Ability
Silent Stream Dweller
Tailed Frogs lack eardrums, an adaptation that helps them navigate and hunt in noisy, rushing water environments.
Ability
Enduring Youth
Tailed Frogs' tadpoles can take up to four years to grow into frogs, allowing them to thrive in cold mountain streams.
Ability
Unique Mating
Tailed Frogs' males have a unique "tail" (a copulatory organ) for internal fertilization in swift currents.
