NORTHERN ROUGH-SKINNED NEWT
Taricha granulosa
DESCRIPTION
Northern Rough-Skinned Newt (Taricha granulosa) is commonly known as the Rough-Skinned Newt. This amphibian is characterized by its rough, warty skin and a striking coloration that ranges from olive to brown, often with a yellow or orange belly. They are primarily aquatic during the breeding season but can be found in moist terrestrial environments during the rest of the year, showcasing a fascinating dual lifestyle.
FUN FACTS
- Northern Rough-Skinned Newts are known for their remarkable ability to regenerate lost limbs, a trait that is quite rare among vertebrates
- This regenerative capability allows them to recover from injuries that would be fatal to many other species
- | During the breeding season, males perform elaborate courtship displays, which include swimming in circles and showing off their bright coloration to attract females
- This behavior is not only fascinating to observe but also plays a crucial role in their reproductive success
