But if you want to be nit-picky fish DO graze on seaweed (being the general term for oceanic plants/grasses). True the ecology for such organisms is different, but the ocean is a different ecosystem altogether so it's useless arguing semantics. Fish graze and eat greens available to them, that much is true.
Not really, Algae don't bear seeds, have rudimentary root structure (if at all), and ancestral organelles. They're in between what we would consider true plants and monerans/protists. The only things they have that most people recognize as plant like features are cell walls and chloroplasts, neither of which are Plantae specific. Hell, "seaweed" and "kelp" aren't even Plants, they're technically protists. But, this is really damned pointless, lol, I just wanna feel like my years studying Biochem weren't wasted. :redface:
But, seriously, what "grazing" fish do we eat? All the fish I can think of that we eat are predators, except for maybe sardines or anchovies, and those are freakin' nasty.
