The genus Taricha consists of four species of highly toxic newts in the family Salamandridae. [1] [2] Their common name is Pacific newts, sometimes also western newts [3] or roughskin newts.

Four species of newts of the genus Taricha are found in California. All are similar in appearance. In some areas you can use the range maps to identify the species that occurs in your area: South of Santa Cruz, north of Pt. Arena, in the central part of the Sierra Nevada mountains, and in a few other regions, only one species occurs.

Working with others to conserve, protect and enhance fish, wildlife, plants and their habitats for the continuing benefit of the American people.

The rough-skinned newt or roughskin newt (Taricha granulosa) is a North American newt known for the strong toxin exuded from its skin.

These newts, distributed along the west coast of North America, derive their name from the rough and grainy lumps that adorn the surface of their skin, which are specialized glands that secrete highly potent neurotoxins. One of the defining features of Taricha newts is their neurotoxin-producing skin glands.

Rough-skinned newts (Taricha granulosa Skilton) are large, conspicuous salamanders that can reach lengths of 22 centimeters (8 inches). Newts are distributed along the Pacific Northwest coast from southeastern Alaska to the Bay Area of central California.

The genus Taricha consists of four species of newts in the family Salamandridae. Their common name is Pacific newts, sometimes also western newts or roughskin newts.

Rough-skinned newts produce a powerful toxin, tetrodotoxin, from granular glands located in the skin. The amount of toxin per newt varies geographically, with some regions bearing newts with extreme toxicity and some regions with newts of low toxicity.
