When both are present in a body of water I believe there are. I see them as a taxidermist from time to time. A local biologist says he does too. They will have the physical appearance of one but have the spine count of the other species.

Interestingly the biggest ones I get in are usually hybrids. I'm talking 3 lb. 18 inch fish.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
