Size varies between species, but they are no larger than 10cm (4in). This species has poorly developed teeth, so mainly eats small crustaceans, but will also Diet - Food is scarce thousands of metres down, so itÕs important to be able to eat whatever comesĪlong.Habitat - Gulper eels are found at depths of 500-7,500m.Distribution - They inhabit all temperate and tropical seas.The gulperÕs stomachĬan also expand to accommodate any large meal that it consumes. Physical description - Gulpers have a long, whip-like tail and an enormous mouth, which is loosely-hinged so that it canīe opened wide enough to swallow animals much larger than themselves.Statistics - This species of gulper eel grows up to 60cm (2ft), although some other species can be up to 2m.Gulper/Pelican eel - Eurypharynx pelecanoides Remaining totally dependent on the female for nourishment.
