Ratfish belong to the subclass Holocephali, whereas most other chondrichthyes, such as sharks and rays, belong to the subclass Elasmobranchii. The main differences include the ratfish having a single gill opening, tooth plates for feeding, and a venomous spine on the dorsal fin, in contrast to the multiple gill openings, teeth, and lack of venomous spines in other chondrichthyes.
A "chimera" can also be referred to as a hybrid or a crossbreed.
Small crustaceans, clams, crabs, starfish, whatever is on the sea floor.
Ratfish primarily feed on small fish, crustaceans, and bottom-dwelling invertebrates like worms and mollusks. They are opportunistic feeders and will consume whatever is available in their habitat, including small octopus and squid.

Here's a few that come to mind... Remora, ratfish, rock beauty, rainbow parrotfish, redband parrotfish, ray, rainbow trout.
Chondrichyhyes is the animal class that includes cartilaginous fishes like sharks, rays and chimeras.
