Eurypharyngidae
by J. G. Nielsen, E. Bertelsen and T. W. Pietsch
Elongate, black midwater eels with a long, tapering tail. A special development of head-bones provides these eels with an enormous mouth cavity and pharynx. Length of neurocranium seven or more times in length of mandible. Dorsal fin origin above head. A caudal organ at tip of tail.
Bathypelagic, oceanic fishes at about 1,400-2,800 m. Rather common in tropical and temperate parts of all oceans. Oviparous; the eggs hatch into leptocephalus larvae.
Genera 1.
