massasauga 北美侏儒响尾蛇

The massasauga (Sistrurus catenatus) is a venomous rattlesnake species found in midwestern North America. Like all rattlesnakes, it belongs to the pit viper family. Rattlesnakes receive their name from the rattle located at the end of their tails, which makes a loud rattling noise when vibrated which deters predators or serves as a warning to passers-by. Rattlesnakes are the leading contributor to snakebite injuries in North America, but rarely bite unless provoked or threatened.

北美侏儒响尾蛇(学名Sistrurus catenatus)是一种产于北美中西部的有毒响尾蛇。像所有的响尾蛇一样，它属于蝮蛇家族。响尾蛇的名字来自于它们尾巴末端的响尾音，当振动时，响尾音会发出巨大的咔嗒声，可以吓阻捕食者，也可以作为对过路人的警告。响尾蛇是北美蛇咬伤的主要原因，但除非受到挑衅或威胁，否则很少咬人。
