What it is

Stareaters, also known as snaggletooths, are small fish belonging to the genus Astronesthes. They are part of the stomiid family. These creatures live in the deep sea. They have delicate skin that is easily damaged. Their mouths contain many sharp teeth. These teeth are needlelike and curve inward. A distinctive feature is the chin barbel. This appendage glows with red light.

Where it lives

These fish inhabit the deep ocean. They are found in dark waters far below the surface. The genus includes forty-eight recognized species. Fossil evidence suggests they have existed for millions of years. Remains from the Middle Eocene in Georgia were once linked to this group. They are now classified under a different genus called Azemiolestes. A potential fossil from Iran dates to the Late Eocene or Early Oligocene.

How it lives

Stareaters are predators in the deep sea. They hunt small prey items. The fish use a specialized hunting strategy. A red bioluminescent barbel hangs from their chin. This light acts as a lure. It attracts curious small animals into striking distance. Once prey is close, the fish snaps its jaws. The sharp curved teeth secure the catch. Their delicate skin requires care in such high-pressure environments.
