The eastern newt (Notophthalmus viridescens) is a common newt of eastern North America. It frequents small lakes, ponds, and streams or near-by wet forests. The eastern newt produces tetrodotoxin which makes the species unpalatable to predatory fish and crayfish. It has a lifespan of 12 to 15 years in the wild, and may grow to five inches in length. These animals are common aquarium pets, being either collected from the wild or sold commercially. The striking bright orange juvenile stage, which is land-dwelling, is known as a red eft. Some sources blend the general name of the species and that of the red-spotted newt subspecies into eastern red-spotted newt (although there is no "western" one).
