Ostorhinchus is a genus of ray-finned fish in the family Apogonidae native to the Indian and Pacific Oceans.[1]
The etymology of the word Ostorhinchus is Greek, with Ostor- stemming from ὀστέον (bone), and -rhinchus stemming from ῥῠ́γχος (Ancient Greek) or ρύγχος (Modern Greek), the meaning of which can be beak. The latter refers to the genus' advanced boned jaw.[2]
