Other Names: Atlantic Barracudina
A freshly caught specimen of Lestidium longilucifer from off NW Western Australia (arrow indicates pelvic-fin origin). Source: Australian National Fish Collection, CSIRO, Fig. 1B, in Ho et al. (2020) Zootaxa 4767(1): 71-88. License: CC by Attribution-NonCommercial-ShareAlike
Summary:
A slightly translucent barracudina with a greyish back, a blackish top of head and lower lips, body above anal-fin base to the caudal fin base silvery white, upper abdominal cavity black with fused peritoneal sections, abdomen silvery-white below, a slightly blackish caudal fin, and the other fins clear.
The luminescent duct extends along the ventral surface beyond the anterior margin of the eye, and the jaws are relatively short.
In Australia, this species was previously referred to as Lestidium atlanticum.
