Poromitra megalops

This species has a circumtropical distribution (Ebeling and Weed, 1973). In the western North Atlantic north of 15°N, it has been taken in the Gulf of Mexico, the western part of the northern Sargasso Sea, and in temperate waters east of 55°W between 40° and 50°N. Four specimens were taken in the Ocean Acre, two of these in discrete-depth, noncrepuscular samples from the paired cruises. They include one 20-mm juvenile and three subadult males, 35–45 mm.

The juvenile was taken at night in September in a discrete-depth sample at 894–925 m. One subadult was taken in April by an open net fishing to 750 m; the other two were caught in June during the day, one in a discrete-depth sample at 970–1060 m, the other in an oblique haul from 970 m.

Atlantic: at tropical latitudes, as far north as 47.7°N

Mesopelagic species, trawled at depths below 400 m.
