地球上有许多神秘的河流，比如亚马逊河流域，这个神秘的亚马逊河，生存着许多稀有物种，很多动物在这里繁衍生息，一直在这里生活，其中有一种让人害怕的物种就生活在亚马逊河中，这个物种就是——食人鱼。

食人鱼又被人们成为食人鲳，是一种体型较小的群居型鱼类，食人鱼经常一起出去觅食，他们凭借着自己灵活的神=身形，以及尖锐的牙齿，给水里的其他鱼类造成了很大的威胁，每次在他们盯准目标的时候，就会蜂拥而至，几乎在很短的时间之内，食物就会被它们咬成白骨。llllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllll

很多不小心落入水中的陆地动物，也都曾被它们袭击，所以很多人一直以为，这话危险的水中杀手可能早已成为了亚马逊河的霸主了，但实际上，食人鱼在亚马逊河中也是有天敌存在的，食人鱼的天敌就是电鳗。

电鳗是一种喜欢独处的水生动物，每次在遇到危险的时候，这种鱼都能够释放出大约到伏的电压，而如此强大的电压，可以轻松杀死30到上百条的食人鱼，所以在亚马逊河流域中，电鳗几乎是 的存在。

其实不仅仅是食人鱼不敢招惹电鳗，其他很多凶猛的水生动物也不敢去招惹电鳗，每次遇到电鳗的时候，食人鱼都会立马一哄而散，群居的食人鱼确实非常凶残，但是也有独居的食人鱼，独居的食人鱼个头较大，比较害羞，一般也不会主动攻击。lllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllll
