Quick Summary

The Eurypharyngidae family, also known as gulper eels, are deep-sea fish characterized by their enormous mouths, which are often longer than their bodies. These fish have soft bodies, tapered forms, and long tails. Their stomachs are highly expandable, allowing them to consume large prey. Gulpers are typically black and some possess light-producing organs. While some species can reach lengths of 1.8 meters (6 feet), a significant portion of this length is their tail. They are found at depths of 2,700 meters (9,000 feet) or more.1
