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.
生息地: Mountain regions
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.

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.
Tailed Frogs lack eardrums, an adaptation that helps them navigate and hunt in noisy, rushing water environments.
Tailed Frogs' tadpoles can take up to four years to grow into frogs, allowing them to thrive in cold mountain streams.
Tailed Frogs' males have a unique "tail" (a copulatory organ) for internal fertilization in swift currents.
Tadpoles graze on algae, while adult frogs mostly hunt small insects found in their streams.
年齢による違い: Tadpoles primarily eat algae and diatoms, while adults switch to preying on aquatic insects and other small invertebrates.
Thamnophis sirtalis
Snakes hunt them near stream edges.
Oncorhynchus clarkii
Trout prey on tadpoles and young frogs.
Hydropsyche betteni
Adult frogs eat their larvae.
Pteronarcys californica
Adult frogs eat their nymphs.
足の指が膜で繋がっているのが特徴で、通常は泳ぐために役立ちます。
単独行動をとる動物は、繁殖や子育ての時を除き、生涯のほとんどを1匹で生活します。
この特性は、主に昆虫やその他の小型無脊椎動物を食べる生物を示します。
この生息環境は、高い標高、急な斜面、多様な気候帯を特徴とする山岳地帯で見られる種を示します。
昼行性の動物は主に日中に活動し、通常は夜間に休息や睡眠をとります。
淡水の生息地には、川、湖、池、湿地などの塩分を含まない水辺の環境が含まれ、多くの生物にとって不可欠な場所です。
絶滅危惧とは、その種が近い将来、野生において絶滅する危険性が非常に高いことを示しています。
