Summary ⁷

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

Lifespan, longevity, and ageing ⁸

Observations: Longevity in captivity is probably underestimated. One animal caught as an adult lived 3.5 years in captivity (http://www.pondturtle.com/). Based on size and growth rates, the average longevity in the wild is estimated to be 12 years (http://amphibiaweb.org/).
