elephant fish

The term "elephant fish" can refer to a few different aquatic animals. Primarily, it denotes Callorhynchus callorhynchus, a chimaeroid fish characterized by a distinctive, elongated, and mobile snout. This fish belongs to the family Callorhinchidae, which are also known as elephant fishes due to this unique snout.12

More broadly, "elephant fish" can also refer to any of the various other chimaeras. Chimaeras, also known as ghost sharks or ratfish, are cartilaginous fish related to sharks and rays, belonging to the subclass Holocephali within the class Chondrichthyes. They possess cartilaginous skeletons, a single gill opening on each side of their body covered by a flap, and males have claspers derived from their pelvic fins. Some species of chimaeras, like the elephant fish, have unusual snouts. These fish are found in temperate to cold waters worldwide and feed on small fish and invertebrates.123
