Rough-skinned newt
The rough-skinned newt (''Taricha granulosa'') is a North American newt known for the strong toxin exuded from its skin.
== Appearance ==
A stocky newt with rounded snout, it ranges from light brown to olive or brownish-black on top, with the underside, including the head, legs, and tail, a contrasting orange to yellow. The skin is granular, but males are smooth-skinned during breeding season. They measure 6 to 9 cm in snout-to-vent length, and 11 to 18 cm overall.〔 They are similar to the California newt (''Taricha torosa'') but differ in having smaller eyes, yellow irises, V-shaped tooth patterns, and uniformly dark eyelids.〔 Males can be distinguished from females during breeding season by large swollen vent lobes〔 and cornified toe pads.〔
