Genus Account
The genus Rhyacotriton contains 4 species of small salamanders (up to 11.7 cm in length) that are very similar in appearance and habitat. All of them occur in cool, old-growth coniferous forests of the U.S. states of California, Oregon, and Washington. They inhabit clear, cold streams, springs, and adjacent terrestrial habitat. The Rhyacotriton (except R. variegatus) are completely protected in the states in which they occur and can only be collected with scientific permits. This essentially makes them unavailable and/or illegal to the private hobbyist. The required temperature range of 5-15°C (41-59°F) also makes them impractical to keep in captivity.
