| synonyms_ref = [1] }} Vinciguerria lucetia is a species of marine ray-finned fish in the genus Vinciguerria known by the common name Panama lightfish. It is a small bioluminescent fish, with two rows of tiny photophores along its body. It is very abundant in the tropical IndoPacific where it makes large vertical migrations each day. DescriptionVinciguerria lucetia is a small fish growing to a maximum length of about {{convert|5|cm|in|0|abbr=on}}. It is an elongated, laterally compressed species with a disproportionately large head which is compressed and conical, with a wide mouth and pointed snout. There are photophores on the head and two lateral rows of pearl-like photophores on the underside of the body. The dorsal fin is short and consists of thirteen to fourteen soft rays. The origin of the anal fin, which consists of fourteen to fifteen soft rays, is below the rear of the dorsal fin. The pectoral fins are set low on the body and the caudal fin is deeply forked. The dorsal surface of this fish is blackish, with a few dark-coloured transverse stripes, and the flanks and belly are silvery. There is a black spot at the tip of the tail.[2]Distribution and habitatVinciguerria lucetia is found in the equatorial water mass of the western Central Pacific and the Eastern Pacific at depths between about {{convert|100|and|500|m|ft|-2|abbr=on}}.[4] This fish is one of several that dominate the fauna of the Southern California Bight and which tend to make diel vertical migrations, rising to near the surface to feed at night and descending again to remain quiescent by day.[3]EcologyVinciguerria lucetia is an epipelagic and mesopelagic species. It is oviparous, the eggs and larvae drifting as part of the plankton.[4] The photophores appear during the course of metamorphosis from larval to juvenile fish; these may be involved in camouflage, species or sexual identification or prey attraction. This fish feed on copepods, krill and sergestid shrimps, crustaceans which also tend to make diel vertical migrations.[3]References1. ^1 {{cite WoRMS |author=Bailly, Nicolas |year=2015 |title=Vinciguerria lucetia (Garman, 1899) |id=274961 |accessdate=8 February 2016}} {{Taxonbar|from=Q1109735}}2. ^{{cite book|title=The Fishes of the Indo-australian Arcipelago |url=https://books.google.com/books?id=E50eAAAAIAAJ&pg=PA119 |publisher=Brill Archive |pages=119–120 |id=GGKEY:6JSRCF1TTR1}} 3. ^1 {{cite book|author1=Dailey, Murray D.|author2=Reish, Donald J.|title=Ecology of the Southern California Bight: A Synthesis and Interpretation|url=https://books.google.com/books?id=JJobUEvPSwAC&pg=PA484 |year=1993 |publisher=University of California Press |isbn=978-0-520-07578-8 |pages=484–485}} 4. ^1 {{cite web |url=http://eol.org/pages/591807/overview |title=Vinciguerria lucetia |work=Encyclopedia of Life |accessdate=8 February 2016}} 2 : Vinciguerria|Fish described in 1899 |
