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.
