Rhyacotritonidae – Torrent salamanders
Endemic to the North-west US; until 1992 were classified in family Ambystomatidae
A small group of salamanders found in the western United States and Canada. They are adapted for life in fast-flowing streams and rivers, with a streamlined body shape and powerful hind legs for swimming. Torrent salamanders are typically small, with a total length of less than 15 cm, but some can grow up to 20 cm (8 in).
They have a distinctive appearance: a broad head, small eyes, and a short, flattened tail. Torrent salamanders are carnivorous, feeding on insects, worms, and other small invertebrates. They are found in various aquatic habitats, including streams, creeks, and waterfalls. Torrent salamanders are not widely known or studied, and little is known about their behavior and ecology. Some species are threatened or endangered due to habitat destruction, pollution, and other human activities.
