Ostorhinchus noumeae is a species of cardinalfish, a group of small, generally brightly colored fish that are common in tropical and subtropical waters around the world.
Description & Characteristics
Ostorhinchus noumeae is a relatively small fish, with a maximum size of around 10 cm. It is characterized by its elongated, cylindrical body, with a slightly compressed head. Its color is typically reddish-brown, with darker bands running along its flanks. This species has large eyes, a small mouth, and a single dorsal fin with 6-7 spines and 9-10 soft rays.
Habitat and Occurrence
Ostorhinchus noumeae is found in shallow coastal waters, typically in depths ranging from 0.0 to 2.0 meters. It prefers habitats with rocky substrates, coral reefs, and seagrass beds. This species is commonly encountered in the marine zone, particularly in coastal areas. Its distribution is limited to the waters around New Caledonia, where it is a relatively common species.
Taxonomy
Ostorhinchus noumeae belongs to the Apogonidae family, commonly known as cardinalfishes. This family is part of the order Kurtiformes, which is in turn classified within the Class Teleostei. This classification places Ostorhinchus noumeae within a diverse group of bony fishes, highlighting its evolutionary relationship with other species in the order and class.
Feeding
Ostorhinchus noumeae is a carnivore, primarily feeding on small invertebrates like plankton, crustaceans, and worms. Its diet reflects its adaptation to life in shallow, coastal waters, where these food sources are readily available.
