 Rhyacotritonidae
Rhyacotritonids are relatively small salamanders (body length under 5 inches) having short tails and small heads with eyes proportionally large and prominent.
Geographic variation and speciation in the torrent salamanders of the genus Rhyacotriton (Caudata: Rhyacotritonidae).
This genus formerly was placed in the families Ambystomatidae and Dicamptodontidae, but the phylogenetic analyses of Larson (1991) and Larson and Dimmick (1993) indicate that Rhyacotriton is only a distant relative of the other salamanders placed in these families.

 Caudata
An advantage of the phylogenetic tree presented here is that it maintains monophyly of the salamanders having internal fertilization of eggs (extant families of the suborder Salamandroidea; mode of fertilization is not known for extinct salamanders of this suborder), which is strongly supported by the characters derived from cloacal anatomy (see Sever, 1991a, 1991b).
The weight of the phylogenetic evidence places the Amphiumidae and Plethodontidae as sister taxa, but this result is not statistically significant (see discussion by Larson [1991] and Larson and Dimmick [1993]).
Some extinct species known only from fossils are grouped into the families Batrachosauroididae, Karauridae, Prosirenidae and Scapherpetontidae.

 Rhyacotritonidae (Tihen, 1859) Torrent Salamanders
Torrent Salamanders are small (11cm), semi-aquatic/terrestrial salamanders found exclusively in western North America.
Originally classed in the family Ambysotmatidae, and later moved to Dicamptodontidae, the genus Rhyacotriton was formally placed in its own separate family, Rhyacotritonidae, in 1992 (Good and Wake).

 Amphibians and Reptiles of Oregon
Of these, nine species are found to display at least one type of anti-predator mechanism.
These species are derived from a total of five families including; Ambystomtidae, Dicamptodontidae, Rhyacotritonidae, Salamandridae, and Plethodontidae.
Of this 450 salamanders, approximately 19 live here in Oregon.

 ASIH 1997 Joint Meetings - Live Herp Display
The high rainfall and cool climate of the west coast supports a number of endemic taxa of amphibians, including the primitive, yet specialized tailed frog ( Ascaphus truei, Ascaphidae); the torrent salamanders (4 species of Rhyacotriton, Rhyacotritonidae); and the impressive giant salamanders (4 species of Dicamptodon, Dicamptodontidae).
Many species of native herps from the Northwest will be displayed.
A variety of reptiles and arid-adapted amphibians inhabit the Great Basin east of the Cascade divide.

Several descriptions of habitat associations have been documented for these species, however most of these have been based either predominantly or exclusively in harvested forests.
The forests of the Pacific Northwest host a unique and environmentally sensitive stream-amphibian fauna, including tailed frog (Ascaphus truei Stejneger) and a species from each of the salamander families Dicamptodontidae and Rhyacotritonidae.

 Dicamptodontidae
Geographic variation and speciation in the torrent salamanders of the genus Rhyacotriton (Caudata: Rhyacotritonidae).
Dicamptodontid salamanders resemble ambystomatids but attain larger adult sizes (up to about 6 inches in body length excluding the tail).
The family Rhyacotritonidae formerly was recognized as the subfamily Rhyacotritoninae of the family Dicamptodontidae, but was given family-level status by Good and Wake (1992) following evidence that the Dicamptodontidae as formerly recognized was not monophyletic (Larson, 1991; Larson and Dimmick, 1993).

 Morphology
The family Rhyacotritonidae was split into four species based on variation among proteins between populations (Good and Wake 1992.
There are four currently recognized species within the Rhyacotritonidae, R. cascadae, R. kezeri, R. olympicus, and R. variegatus, with R. variegatus being the only species that makes it into California.
Larvae are of the stream type, having very short lungs and adult proportions (Stebbins 2003).
