Taricha granulosa
Rough-skinned Newt / Triton rugueux


Rough-skinned Newt

Description
Even for a newt, the Rough-skinned Newt has very rough, warty skin. Generally it is light brown to black on top with a yellow or orange belly. Adults can grow to over 20 cm in total length.

Confusing Species
There are no other newts in British Columbia to confuse this species with.

Distribution
The Rough-skinned newt is limited to the Pacific coast of British Columbia as far north as southern Alaska. To the south it occurs along the coast to northern California. The Rough-skinned Newt has the distinction of being found farther north than any other salamander in North America.

Habitat
The preferred habitat of the Rough-skinned Newt is ponds, lakes and slow-moving streams. Terrestrial efts can be found in the adjacent humid forests.

Reproduction
Breeding generally occurs in the spring. Newts are known for their elaborate courtship displays. The female lays her eggs one at a time on submerged plants. Within one to two months the eggs hatch and the larvae transform into efts late in the summer at roughly 5 cm total length. Some larvae may not transform until the following summer, when they may be over 7 cm long.

Natural History
Terrestrial efts can be found wandering about on cool, humid days, in search of food. Newts eat a variety of insects and other invertebrates. Newts contain toxins in their skin which are lethal to most predators except Gartersnakes. When threatened by a predator they assume a posture which displays the bright colour of the underside. This presumably warns the predator that they are toxic.

Conservation Concerns
There is no evidence of a decline in Rough-skinned Newts.
