Lingcod are not sculpin - Hexigramids, same as Greelnling. Cabezon are sculpins (cottids) however.

Bullhead are usually a common name for catfish when sold in the store. Pacific Staghorn sculpins would be very difficult to harvest in quantities suffiecient for commercial sale - You sure you saw those and not catfish?

Theres one in every crowd. You are correct in that a Ling is not a Sculpin. Using the word "Family" I suppose was not the right choice as apparently the rocket scientists of the crowd will call you on it. So just to clear things up, all of the above mentioned fish are of the same "Order" of fish,which to the average joe means that when mother nature decided to make multiple families of said order of fish, she used the same skeleton, relatively speaking. This IS obvious to the average person just by looking at them side by side.

Cabi is to bullhead what Envoy is to Trailblazer, the Lingcod would be a Tahoe.

Feel free to split some more hairs if you must.

Right on Turbu - Next thing we know, they will be selling toe-biters in the stores too.

So you say Cabizon and Lings are both are Chevrolets - I figured a Cabizon to be more of a Plymouth, they have that blue-green meat similar to colors of those old '60s Baracudas. And Lingcod must be Ramblers - they used to have a Marlin that had a big ugly front end like a Ling. Maybe a Tiger Muskie is a Toyota - a hybrid sort of like like a Prius. Now, for the non-bony fishes, you definitely could have Chevrolets there, all related to a Stingray.
