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.
