A: jawless fish
Clown fish do have jaws, so they are not a jawless fish.
Most fish are not jawless. There is a small group of very primitive fish called Jawless fish (Agnatha). However, they make up a very small proportion (<1%) of the fish species on earth. Jawless fish are things like lamprey and hagfish. All other fish, like trout, salmon, tuna, sharks, rays, cichlids, goldfish, etc, etc, have jaws. See the related link for more information on the primitive jawless fish.
Hagfish are cartilaginous, meaning their skeletons are made from cartilage. FALSE what the person just wrote is wrong. Hagfish are neither cartilaginous or bony fish. Although they have cartilage in their bodies, they belong to a third category called Jawless fish. Jawless, cartilaginous, and bony are the 3 types of fish.

Jawless fish have an internal cartelagenous endoskeleton.
