Living mainly in South American rivers that feed the Amazon, Anacondas spend most of their time in the water.

水蟒主要栖息在滋润亚马逊地区的南美众多河流中，这使得它们生命中的大多时间都生活在水里。

Although real anacondas are not nearly as large and rarely eat people, they are impressive creatures nonetheless.

Since their body weight is supported by the water, even the largest, heaviest anacondas are still effective predators.

因为它们的身体重量由水来支撑，所以即使是最大的最重的水蟒也可以是战斗力超强的食肉动物。

Anacondas live in swamps, marshes, and slow-moving streams, mainly in the tropical rain forests of the Amazon and Orinoco basins.

它们生活在沼泽，湿地和水流缓慢的溪流中，主要分布在亚马逊热带丛林和奥里诺科河盆地。

Anacondas eat virtually anything unfortunate enough to get caught in their grip, including other snakes, fish, deer, and even small jaguars.

事实上水蟒会吃掉任何足够倒霉的被它逮到的猎物。包括其他的蛇类，鱼，鹿子，甚至是小型的美洲虎。

Modern large-mouthed snakes, such as boas and anacondas, can eat large prey because their jaw joints are positioned well behind their skulls, allowing the snakes to open their mouths very wide.

现代阔口蛇，像蟒蛇和水蟒，能吃大的猎物是因为它们的颌关节恰位于头骨的后面，能使蛇的嘴张得非常宽。
