世界十五种毒物.ppt

Fifteen of the world s most poisonous animal 世界上十五种最毒的动物 子弹蚁 Paraponera is a genus of ant consisting of a single species, commonly known as the lesser giant hunting ant, conga ant, or bullet ant (Paraponera clavata), named on account of its powerful and potent sting, which is said to be as painful as being shot with a bullet. It inhabits humid lowland rainforests from Nicaragua south to Paraguay. The bullet ant is called Hormiga Veinticuatro or 24 (hour) ant by the locals, referring to the 24 hours of pain that follow being stung. 子弹蚁是由一种属的蚂蚁组成一个单一的物种，俗称小巨人狩猎蚂蚁，康蚂蚁，或子弹蚁,因其强大的颚和强有力的刺痛被命名，据说这痛苦像是被子弹打中一样。它栖息潮湿的低地热带雨林，从尼加拉瓜南部到巴拉圭。子弹蚁被本地人称为“24小时蚂蚁”，指的是被蜇后会伴随着24个小时的痛苦。 箱形水母 Box jellyfish (class Cubozoa) are cnidarian invertebrates distinguished by their cube-shaped medusae. Box jellyfish are known for the extremely potent venom produced by some species: Chironex fleckeri, Carukia barnesi and Malo kingi are among the most venomous creatures in the world. Stings from these and a few other species in the class are extremely painful and sometimes fatal to humans 这些透明的海洋生物是热带海滩上的毒物。它们被认为是动物界里非常危险的一种生物，它们的触须包含剧毒，可致人类丧命。而且这种毒液可引起令人无法忍受的剧烈疼痛。箱形水母的触须会向受害者的皮肤里释放很多毒针，每个毒针都包含一种致痛因子，因此它被称为“世上最令人痛苦的毒刺”。马里兰大学医学院皮肤科以前的负责人约瑟夫·波内特博士说：“毫无疑问它们确实那么厉害。子弹蚁简直无法跟它相比。”圣地亚哥动物园爬行动物和两栖动物馆长丹·鲍威尔表示，虽然箱形水母的毒刺看起来就是一个防御工具，但是“它们不仅利用这些毒刺折磨海滩上的人，而且还利用它们捕杀猎物，例如小虾。”因为奋力挣扎的小虾很容易对箱形水母脆弱的身躯产生破坏，因此它必须快速杀死小虾。 响尾蛇和它们的近亲 Rattlesnakes are a group of venomous snakes of the genera Crotalus and Sistrurus[1] of the subfamily Crotalinae (pit vipers). There are 32 known species of rattlesnake, with between 65-70 subspecies,[2] all native to the Americas, ranging from southern Alberta and southern British Columbia in Canada to Central Argentina. Rattlesnakes are predators who live in a wide array of habitats, hunting small animals such as birds and rodents. They kill their prey with a venomous bite, rather than by constricting. All rattlesnakes possess a set of fangs with which they inject large quantities of hemotoxic veno
