The emperor newt, also called the Mandarin newt or Mandarin salamander, is a highly toxic newt native to Yunnan and parts of south China, growing up to 20cm long. It has a ridged orange head with a darker, almost black body and a single orange ridge running down the back to the tip of the tail; the tail and legs are the same orange, which can vary with population, diet and distribution (Wikipedia, general species account).
