We report the occurrence and distribution of lanternfish in relation to oceanographic conditions and attempt to examine whether species associations are spatially different.
A tendency of increasing species number with depth was observed, and since temperature correlates to lanternfish distribution (Brandt, 1983), this result could be associated with the marked thermal structure of the water column.
Lanternfish may be an important prey item for large pelagic species, abundant in longline catches from Vitoria-Trindade seamounts (Olavo et al.
The stomach of a harbor porpoise (Phocoena phocoena), captured in a pelagic drift net fishery off North Carolina was found to contain more than 1900 otoliths of Horned Lanternfish (Read et al.

Two other lanternfishes (the glacier lanternfish [Benthosema glaciale] and the soft lanternfish [Diaphus mollis]), the white barracudina (Arctozenus risso), and the boa dragonfish (Stomias boa) were also present.
The primary prey of this dolphin was the Madeira lanternfish, a myctophid living between 330 and 600 m during the day in slope water and on the continental slope (Backus et al.
The lanternfish also have small otoliths--perhaps smaller than those of any other prey taxa found in the scats.

, and lightfish between the 75- and 300-m isobaths (Hulley and Prosch, 1987), and mantis shrimp in the 20-200 m depth zone (Griffiths and Blaine, 1988)--it is likely that juvenile snoek move farther offshore when anchovy recruits leave the area, i.
