a type of small salamander

One of eight Families of salamanders, only four of which are found in Canada. Unlike most salamanders the skin of newts is not smooth but rough. Most newts go through three life stages rather than just two like most amphibians. The larval newt transforms into a terrestrial stage called an eft. This stage can last 1-3 years before the eft transforms into a largely aquatic adult. Only two species of newts are found in Canada, the Roughskin Newt in British Columbia and the Eastern Newt in eastern Canada.

Newts are small, usually bright-colored semiaquatic salamanders of North America, Europe and Asia, distinguished from other salamanders by the lack of rib or costal grooves along the sides of the body.
