Ostorhinchus capricornis Ostorhinchus capricornis Ostorhinchus capricornis, also known as the Capricorn cardinalfish, is a species of ray-finned fish, a cardinalfish from the family Apogonidae which occurs around reefs in the western Pacific Ocean. "Ostorhinchus capricornis" is dusky yellow in colour, this lightens to bronze or golden yellow on the ventral surfave. It has a black spot around the caudal peduncle and it has two "neon" blue stripes which run through the eye, the lower stripe extending to the posterior edge of the operculum. It grows to a maximum standard length of . It is similar to the yellow cardinalfish ("Ostorhinchus flavus") but
Lanternfish pectoral fins, usually with eight rays, may be large and well-developed to small and degenerate, or completely absent in a few species. In some species, such as those of the genus "Lampanyctus", the pectorals are greatly elongated. Most lanternfish have a gas bladder, but it degenerates or fills with lipids during the maturation of a few species. The lateral line is uninterrupted. In all but one species, "Taaningichthys paurolychnus", a number of photophores (light-producing organs) are present; these are paired and concentrated in ventrolateral rows on the body and head. Some may also possess specialised photophores on the caudal peduncle,
