The eastren esk (Notophthalmus viridescens) is a common esk o eastren North Americae. It frequents smaw lochs, ponds, an streams or near-bi wet forests. The eastren esk produces tetrodotoxin which maks the species unpalatable tae predatory fish an crayfish.[2] It haes a lifespan o 12 tae 15 years in the wild, an mey grow tae five inches in lenth. These ainimals are common aquarium pets, bein either collectit frae the wild or sauld commercially. The strikin bricht orange juvenile stage, which is laund-dwellin, is kent as a red eft. Some sources blend the general name o the species an that o the reid-spottit newt subspecies intae eastren reid-spottit esk (awtho thare is nae "wastren" one).[3][4]
