Ostorhinchus maculiferus, commonly known as the Hawaiian Spotted Cardinalfish or ʻUpāpalu, is a species of reef-associated cardinalfish in the family Apogonidae. Endemic to the Hawaiian Islands, it occurs across both the main and northwestern island chains, typically inhabiting rocky reefs, caves, and crevices. Known for its pale body coloration with rows of dark spots and large eyes adapted for nocturnal activity, this species plays an important role in reef ecosystem dynamics. Juveniles are often found in tide pools and shallow flats, later transitioning to deeper waters as they mature. ʻUpāpalu holds cultural significance in Hawaiʻi, having traditionally been used as a food fish and caught with nets or traps. Although currently listed as Least Concern by the IUCN, O. maculiferus remains vulnerable to threats such as climate change, habitat degradation, and overfishing.
