Description

The tailed frogs are two species of frogs in the genus Ascaphus, the only taxon in the family Ascaphidae /æˈskæfɪdiː/. The "tail" in the name is actually an extension of the male cloaca. The tail is one of two distinctive anatomical features adapting the species to life in fast-flowing streams. These are the only North American frog species that reproduce by internal fertilization.

General Info

Lifespan

10-15 years

Diet

Tailed frog's dietary regime primarily relies on small invertebrates. Its consumption significantly includes varied aquatic insects, with special preference for caddisfly and mayfly larvae, ensuring a species-specific, well-balanced nutrition.

Appearance

Tailed frog is a small amphibian with an elongated body covered in smooth, slick skin. This animal's base color is typically a muddy brown, providing exceptional camouflage against rocky stream beds. Significantly, it boasts an internal tailed fin that stretches from its rear to its abdomen, unique among frogs. Its distinctive, foreboding eyes are large and bulging, accentuating the rounded shape of its head.

Behavior

Tailed frog is a nocturnally active, semi-aquatic species, showing a remarkable ability to inhibit metabolic processes within cold temperatures in its mountain habitat. It is solitary, except during mating season. Dominated by a strong territorial instinct, males advertise their presence through unique vocalizations and aggressively guard their regions from intruding males.
