Saccopharynx is a genusofdeep-seaeels with large mouths, distensible stomachs and long, scaleless bodies. Commonly, these fish are called gulpersorgulper eels. It is the only genus in the family Saccopharyngidae, and is part of the derived lineage of the "saccopharyngiforms," which includes other mid-water eel species. The name is from Latinsaccus meaning "sack" and Greek φάρυγξ, pharynx.
They are generally black in color, and can grow to lengths of 2 m (6.5 feet). They have been found at depths of 1,800 metres (5,900 ft), and are known to inhabit the eastern and western Atlantic Ocean and the Gulf Stream.[1] Their tails are tipped by a luminous, bulb-shaped organ. The exact purpose of this organ is unknown, although it is most likely used as a lure, similar to the escaofanglerfish.
