Coastal tailed frog

Ascaphus truei

Summary 6

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.

Lifespan, longevity, and ageing 7

Maximum longevity: 14 years (wild)
Observations: In the wild, these animals may live up to 14 years (Smirina 1994). Some speculate that females may live 15-20 years and males somewhat less. In inland populations females appear to bread every other year, while in coastal populations may breed every year (http://amphibiaweb.org/).
