Hi, I'm Nick. I built Herp Calendar on my own and I keep it free, with no ads. If it has helped you find a herp this season, a small tip goes straight into the hosting and the data work. Only if you can spare it. Either way, I'm glad you're here.

Dicamptodon tenebrosus

Look, don't take. Many states regulate collecting reptiles and amphibians. Photograph it, log it on iNaturalist and leave it where you found it.

Description

The coastal giant salamander (Dicamptodon tenebrosus) is a species of salamander in the genus Dicamptodon (Pacific giant salamanders). The coastal giant salamander can reach up to 33 cm (13 in) in total length as a terrestrial adult, and 35.5 cm (14.0 in) in paedomorphic forms, making it the largest terrestrial salamander in North America.Wikipedia ↗

Habitat

The coastal giant salamander is endemic to the Pacific Northwest, found in Northern California, Oregon, Washington, and southern British Columbia. Aquatic stages are found in clear, cool or cold, well-oxygenated streams, and sometimes also in mountain lakes and ponds.Wikipedia ↗

When it's active

A female coastal giant salamander will lay her eggs in moderate to slow flowing mountain streams under rocks and crevasses, hatching in early to mid spring. In the larval stage, coastal giant salamanders will feed on small macroinvertebrates such as insect larvae as well as small fish and mollusks.Wikipedia ↗
