Nezumia

Nezumia is a genus of small, deep-sea fish belonging to the Macrouridae family, commonly known as grenadiers or rattails. These fish typically inhabit deep ocean environments and are characterized by elongated bodies, large eyes, and a tapering tail resembling a rat's tail. They play a role in deep-sea ecosystems, feeding on invertebrates and small fish. Due to their habitat, species of Nezumia are often studied through deep-sea research and are less known compared to shallow-water fish. They are important for understanding deep-sea biodiversity and ecological dynamics.
