Thread: Can shellcrackers really crack shells?

Really, I don't see how they could. They don't look all that much different from gills, and I don't think a bluegill could crack any shells. Besides, what kind of shells are they supposed to crack anyway?

Actually, Cartman .... YES, they can crack shells. They have crusher plates in their throat, that they use to crush snail shells & other shelled critters.

Check out "Habitat & Biology" portion of this article : Redear Sunfish (Shellcracker) - Freshwater Fish Facts

Yes in my local lakes redear feed on freshwater clams(Lopez lake, Cachuma lake) also i've read they make a clacking sound with those crushers during spawning season

They also can mash up smaller hard crayfish and water beatles into pulp...
