南美响尾蛇（Crotalus durissus）是一种分布在南美洲的响尾蛇。牠们是属内分布最广的物种^[2]，并在其出没的一些地区引发毒蛇咬伤的救治难题。^[3]其下已发现了8个亚种。^[4]

特征

南美响尾蛇可以长达1.8米，颈部到头部有两道明显的黑线（其实视脊椎骨的突起痕迹）。

分布

除了厄瓜多尔及智利，南美响尾蛇分布在南美洲的所有国家。不过，牠们的分布地却是断断续续的^[2]，在北部的哥伦比亚、委内瑞拉、圭亚那、苏里南、法属圭亚那及巴西北部有一些孤立的群落。牠们出没于哥伦比亚及巴西东部至秘鲁东南部、玻利维亚、乌拉圭、巴拉圭及阿根廷北部。^[5]牠们也在加勒比海的一些岛上生活，包括塔玛林多及阿鲁巴。^[2]

栖息地

南美响尾蛇喜欢大草原、卡丁加群落及喜拉多。牠们也曾在委内瑞拉西北部的海岸丛林出没。在巴拉圭的格兰查科，牠们栖息在较干旱及多沙的地方。^[2]

毒素

南美响尾蛇的毒素有如在玩俄罗斯轮盘。成年响尾蛇的毒素效果只会破坏血液细胞和组织，但年幼响尾蛇还没有能发出警告的响环，因此他们的毒素还会让肌肉弯曲痉挛，并攻击呼吸系统，导致呼吸衰竭。效果较强的毒素可弥补年幼响尾蛇无法发出警告的缺陷。

亚种

亚种^[4]	命名者^[4]	俗称	分布
C. d. cumanensis	Humboldt, 1833	委内瑞拉响尾蛇^[6]
C. d. durissus	Linnaeus, 1758	南美响尾蛇^[2]（指名亚种）
C. d. marajoensis	Hoge, 1966
C. d. maricelae	García Pérez, 1995
C. d. ruruima	Hoge, 1966		分布在委内瑞拉的罗赖马山；在巴西也有发现一些标本。^[2]
C. d. terrificus	(Laurenti, 1768)		分布在巴西的卡斯卡韦尔。^[6]
C. d. trigonicus	Harris & Simmons, 1978
C. d. unicolor	Lidth de Jeude, 1887	阿鲁巴响尾蛇^[7]	分布在委内瑞拉对出的阿鲁巴岛上。^[7]
C. d. vegrandis	Klauber, 1941	乌拉岗响尾蛇^[7]	分布在委内瑞拉的摩纳加斯。^[7]

分类

圭亚那响尾蛇原先被命名为C. d. dryinus^[5]，现已被认为是指名亚种的异名。正确来说，以往南美响尾蛇的指名亚种后来成为了C. simus的指名亚种，而圭亚那响尾蛇则改为南美响尾蛇的指名亚种。^[2]C. d. collilineatus及C. d. cascavella都被认为是C. d. terrificus的异名。^[8]^[9]
