Perhaps the best example of this dental diversity can be seen in cichlids.

最能呈现这多样性的例子应该是慈鲷。

But here, almost every corner of the ecosystem is occupied by a different species of cichlid.

但在这里，几乎生态系统的个角落都被不同的慈鲷占据。

丽鱼科鱼的性别决定非常复杂。

There are over 1,700 cichlid species, many almost identical save for their uniquely adapted jaws which have evolved to eat crustaceans, mollusks, worms, algae, plankton, and even the scales of other fish.

其类超过一千七百，许多类几乎一模一样，但为了吃甲壳动物、软体动物、虫类、藻类、浮游生物甚至其他鱼类的鳞片而化出不同的颔。
