rhyacotriton การใช้

All species of Rhyacotriton are small, with their body lengths being less than 5 inches.
The genera " Dicamptodon " and " Rhyacotriton " were formerly included in this family, but are now usually placed into their own families Dicamptodontidae and Rhyacotritonidae.
In aquatic, cold-water species like the southern torrent salamander ( " Rhyacotriton variegatus " ), the lungs are very small with smooth walls, while species living in warm water with little dissolved oxygen, such as the lesser siren ( " Siren intermedia " ), have large lungs with convoluted surfaces.
