比拉鲁库无疑是最著名的世界上最大的淡水鱼。 这个浑身是鳞的巨人可以达到令人印象深刻的2.3米长，体重达200公斤。 令人难以置信，不是吗？
皮拉鲁库的惊人特点还不止于此：这种鱼非常古老，在2亿多年前恐龙统治地球的时候，它就已经存在了。
这种独特的动物有一个特点，使它有些脆弱：与其他鱼类不同，皮拉鲁库需要到水面上去呼吸。
正是在这个时候，渔民们在亚马逊河面上的独木舟和小船上耐心等待，趁机投下鱼叉，捕捉这个真正的河中巨人。
比拉鲁库鱼的肉质非常鲜美，而且骨头很少，这使得这种鱼成为制作一些亚马逊美食的宠儿，此外还征服了全世界越来越多的人的胃。
最大的淡水皮鱼
皮拉伊巴几乎在所有方面都与皮拉鲁库相似：它的成年平均体重也达到了令人难以置信的200公斤，长度为2.3米。
两者之间的主要区别在于皮肤：皮拉鲁库鱼覆盖着鳞片，而皮拉伊巴鱼是一种皮革鱼。
身体的形状、鳍的位置和皮革的颜色为皮拉巴赢得了一个非常恰当的绰号：它通常被称为 "河鲨"。
除了已经提到的相似之处，皮拉巴的力量和行为也类似于鲨鱼。 这是一种非常坚硬的鱼，通常难以捕捉，并与运动型渔民的鱼钩进行大量的斗争。
piraíba也是亚马逊流域所有河流中的自然物种，但有一定的难度。 由于它有夜间活动的习性，白天通常会捕食其他鱼类来养活自己，而且它是一种有迁徙习惯的动物，要找到piraíba比pirarucu更难。
