Ratfish

A ratfish is a type of cartilaginous fish belonging to the order Chimaeriformes, characterized by a long, slender tail resembling that of a rat. These deep-sea creatures are related to sharks and rays and are known for their distinctive appearance, including large eyes, a blunt snout, and smooth skin. They typically inhabit cold, deep ocean waters and are largely benthic, feeding on small invertebrates and other marine organisms.
