The Holostei, a subclass may be paraphyletic fish have bones, the cartilages are usually with an outer layer of bone. Needle and bowfin, are examples.
I think the Holocephali have cartilaginous skulls and other bones of the skeleton, but could be wrong. This could also be paraphyletic however.
There's A FISH IN THE DRAFT Mississippi River system with the name of a spoon as catfish fish cartilage single paddle.
