The eastern newt (''Notophthalmus viridescens'') is a common newt of eastern North America. They frequent small lakes, ponds, and streams or near-by wet forests. They can coexist in an aquatic environment with small, noncarnivorous fish, as their skin secretes a poisonous substance when the newt is threatened or injured. They have lifespans of 12 to 15 years in the wild, and may grow to five inches in length. These newts are common aquarium pets, being either collected from the wild or purchased. The bright orange juvenile stage, which is land-dwelling, is often known as the red eft. Some sources blend the general name of the species and the red-spotted newt subspecies name into eastern red-spotted newt (although there is no "western" one).〔〔 ==Sub-species== The eastern newt has these subspecies: *Red-spotted newt (''N. v. viridescens'') *Broken-striped newt (''N. v. dorsalis'') *Central newt (''N. v. louisianensis'') *Peninsula newt (''N. v. piaropicola'') 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Eastern newt」の詳細全文を読む スポンサード リンク
