They would almost certainly fall into three main types:grazers,browsers,and tappers.Grazers would be identifiable because their teeth and jaws are specialized to act as combs that brush through the filamentous carpet of algae at the water's edge.Browsers would be algal scrapers with rasps for mouths:mouths specialized for breaking off the tough algal carpet itself.Finally,the tappers could be identified by their sharp teeth and strong heads that cut and pull algae from the rocks.
前面说的大概是一种可以将藻类从岩石上刮下的鱼,这段把这种鱼大体分为三类.请问该如何翻译,特别是grazers,browsers,and tappers这三个种类分别该怎么翻译?
