Lophiiform fish from Usan

Lophiiform fish from Usan


Common monkfish. Usually around 200 mm in total length. Has walking anal fins. Ocgocephalidae, probable genus either Dibranchus or Halieutichthys. The fundamental shape is that of Dibranchus, but I cannot see the details necessary in this low-res image. The close resemblance to Dibranchus would suggest this is the correct genus, if so the species found commonly in the Gulf of Guinea from 45- 1300 m depth is Dibranchus atlanticus. One other species Dibranchus tremendous is found in the region but typically deeper than this survey (750-2300 m). The details necessary to resolve the species are not visible in the photograph.
