TL;DR: In this paper, data from 9 major trawling surveys made around the North Atlantic Basin at slope, rise and abyssal depths provide directly comparable information on deep demersal fish distribution and faunal composition.
Abstract: Data from 9 major trawling surveys made around the North Atlantic Basin at slope, rise and abyssal depths provide directly comparable information on deep demersal fish distribution and faunal composition. 338 species in 57 families and 189 genera are recorded, and semi-diagrammatic maps showing relative abundance both horizontally and vertically for 67 of these are presented. Alepocephalidae, Gadidae, Macrouridae, Moridae and Ophidiidae comprise nearly 2/3 of all species taken. 296 species were taken at slope depths (200–2250 m), 99 at rise depths (2250–4500 m), and 32 at abyssal depths (>4500 m). Diversity and the rate of endemism were highest on the slope. The Norwegian, Caribbean and Mediterranean Basins appear to harbor impoverished versions of the adjacent Atlantic Basin fauna. Each species distribution appeared to be rather exceptional and no repeatable pattern could be found amongst the maps.

TL;DR: A new species of Physiculus, P. caboverdensis n.
Abstract: A new species of Physiculus, P. caboverdensis n. sp., is described from the outer shelf and upper slope of the Cape Verde Islands. This species differs from all other congeners from the Atlantic Ocean by its peculiar dentition, composed of large fang-like teeth in both jaws, interspaced with smaller canine-like teeth, arranged in two series on upper jaw and one on lower. This is the tenth species of the genus to occur in the Atlantic Ocean and the third to be recorded from the Cape Verde Islands.

TL;DR: A fourth, new species of Physiculus is described based on seventeen specimens collected in the surroundings of Saint Peter and Saint Paul Archipelago, equatorial Atlantic, and is distinguished from all its congeners, except P. cynodon and P. karrerae.
Abstract: Three valid species of the genus Physiculus are known from the Brazilian marinewaters. A fourth, new species, Physiculus cirm n. sp.., is described based on seventeen specimens collected in the surroundings of Saint Peter and Saint Paul Archipelago, equatorial Atlantic. A review of the Brazilian species of Physiculus is provided, as well as a key to the species of the genus reported from the Atlantic Ocean. The new species is distinguished from all its congeners, except P. cynodon and P. karrerae, by the large number of longitudinal series of scales (156-189 vs. 70-150). P. cynodon from the Northern Pacific has about 200 longitudinal series of scales, and it differs from the new species by the number of rays of the first dorsal fin (6-8 vs. 10 in P. cynodon), pectoral-fin rays (20-25 vs. 27 in P. cynodon), and the presence of an outer row of large canine teeth on upper and lower jaw. From P. karrerae, which has 134-160 longitudinal series of scales, the new species differs by the presence of scales on the tip of the snout and dorsal-fin membrane, and the number of pectoral-fin rays (20-25 vs. 24-27 in P. karrerae).

TL;DR: Beam trawl, camera sled, and submersible data from 2 000-3 300 m off central California produced similar fish faunal composition, but different density estimates as discussed by the authors.

TL;DR: It is speculated that the difficulty of encountering a host in the vast pelagic biome has restricted the diversity of parasitic copepods that have successfully colonized pelagic fishes.
