About this species

The shortdorsal cutthroat eel is an eel in the family Synaphobranchidae. It was described by Albert Günther in 1887. It is a marine, deep water-dwelling eel which is known from the Indo-Pacific and western central Atlantic Ocean, including Zanzibar, Maldives, Australia, Japan, Suriname, and the Gulf of Mexico. It dwells at a depth range of 900 to 3,000 metres, most often between 1,000 to 2,500 metres, and leads a benthic lifestyle, inhabiting the continental slope. Males can reach a maximum total length of 111 centimetres (44 in).
