Conger and moray are two species of eels that are found in the ocean. They are both long, slender fish with a snake-like appearance. Conger eels can grow up to 3 meters in length and are typically found in deeper waters. Moray eels are smaller, usually reaching a maximum length of 1.5 meters, and are usually found in shallow waters. Both species are carnivorous and feed on small fish, crustaceans, and mollusks.
