So fish and I guess a number of organisms can be classified as either generalist feeders or specialist feeders, and by that we mean, if it’s a generalist, it often can eat fairly broad types of items and dietary items. So it will generally eat cosmopolitan species, so it will be eating a bit of polychaetes or worms, a bit of bivalve, maybe some smaller crustaceans and so on. And then you've got these more specialist feeders that often have mouth parts especially adapted for eating a particular diet, and so they will have a narrower niche of items that they eat.
