The eastern newt or red-spotted newt is a common salamander of eastern North America. Eastern newts dwell in wet forests with small lakes or ponds. They can coexist in an aquatic environment with small, non-carnivorous fish, however, their skin secretes a poisonous substance when the newt is threatened or injured. They have a lifespan of 12 to 15 years in the wild, and may grow to 5 inches in length. The newts are a common aquarium pet, being either collected from the wild or purchased. The strikingly colored (orange) juvenile stage, which is land-dwelling, is often known as the red eft. Some sources blend the common name into eastern red-spotted newt (although there is no "western" one). Some of its subspecies have completely different names, such as broken-striped newt.

Not my best shots, but looking back in the album, they're the best I got on that trip. This animal was spotted in Nescopeck State Park.
