provided by wikipedia EN

The shortdorsal cutthroat eel (Synaphobranchus brevidorsalis, also known commonly as the shortfin cut-throat eel[2]) is an eel in the family Synaphobranchidae (cutthroat eels).[3] It was described by Albert Günther in 1887.[4] 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 (3,000 to 9,800 ft), most often between 1,000 to 2,500 metres (3,300 to 8,200 ft), and leads a benthic lifestyle, inhabiting the continental slope. Males can reach a maximum total length of 111 centimetres (44 in).[3]
