Longnose hawkfish
A monotypic hawkfish with a long snout and grid-like red pattern.
The longnose hawkfish (Oxycirrhites typus) is a marine ray-finned fish from the hawkfish family, Cirrhitidae. It is the sole member of its genus. This fish lives on tropical reefs across the Indian and Pacific Oceans, typically on steep outer reef slopes exposed to strong currents, where it dwells among gorgonians and black corals. It is found at depths of 10 to 100 meters (33 to 328 feet) and reaches a maximum total length of 13 centimeters (5.1 inches). It is also sold in the aquarium trade.
The species was first described in 1857 by Dutch ichthyologist Pieter Bleeker, who gave its type locality as Ambon Island in Indonesia. He placed it in the monotypic genus *Oxycirrhites*, a name combining *oxy* (meaning "sharp" or "pointed") with *Cirrhites*, an alternate spelling of the type genus of the family. The specific name *typus* indicates it is the type species of its genus.
The longnose hawkfish is distinguished from all other hawkfish by its elongated snout, which is about half the length of its head. Its canine teeth are uniform in size and only slightly larger than the inner band of villiform teeth. The dorsal fin has 10 spines and 13 soft rays, with a tuft of cirri at the tip of each spine; the anal fin has 3 spines and 7 soft rays. The body is whitish with a grid of red horizontal and vertical lines.
Its range spans the Indo-Pacific: from the Red Sea and east Africa to Hawaii, French Polynesia, Japan, and Australia. In the eastern Pacific, it occurs from Baja California and the Gulf of California south to Colombia, including the Galapagos, Cocos, and Malpelo Islands. It is uncommon to rare across most of its range and is territorial. It preys on small benthic or planktonic crustaceans. Breeding involves pelagic spawning in distinct monogamous pairs. The species is common in the aquarium trade.

Lore & Background
The longnose hawkfish was first formally described in 1857 by the Dutch ichthyologist Pieter Bleeker, who placed it in the monotypic genus Oxycirrhites. The genus name combines oxy, meaning 'sharp' or 'pointed', with Cirrhites, an alternative spelling of the type genus Cirrhitus. The specific name typus indicates it is the type species of its genus.
This species differs from all other hawkfish in its elongated snout, which fits roughly twice into the overall length of the head. Its canine teeth are of uniform size, only slightly larger than the inner band of villiform teeth. The body is whitish with a grid of red horizontal and vertical lines, and each dorsal fin spine has a tuft of cirri at its tip.
The longnose hawkfish is found on tropical reefs of the Indian and Pacific Oceans, from the Red Sea and east Africa to Hawaii, Japan, Australia, and the eastern Pacific including Baja California and the Galapagos. It inhabits steep outer reef slopes exposed to strong currents, living among gorgonians and black corals at depths of 10 to 100 meters.
Reader's Guide
The longnose hawkfish is significant as the sole member of its genus, Oxycirrhites, making it a distinct lineage within the hawkfish family Cirrhitidae. Its elongated snout is a unique morphological feature among hawkfish, likely an adaptation for feeding on small benthic or planktonic crustaceans, which constitute its prey. The species is uncommon to rare across most of its wide Indo-Pacific range and is territorial, forming monogamous pairs for pelagic spawning. It is also common in the aquarium trade, contributing to its visibility outside its natural habitat. The species was first described in 1857 by Pieter Bleeker from Ambon Island, Indonesia, and its type status within the genus underscores its taxonomic importance. Its presence on steep outer reef slopes among gorgonians and black corals highlights its specialized habitat preferences, and its wide distribution from the Red Sea to the eastern Pacific demonstrates its adaptability across tropical reef systems.

Frequently Asked Questions
What is the Longnose hawkfish?
The Longnose hawkfish (Oxycirrhites typus) is a small marine ray-finned fish in the hawkfish family, Cirrhitidae, and it is the only species in its genus. Dutch ichthyologist Pieter Bleeker first described it in 1857 from material collected at Ambon Island, Indonesia.
Where does the Longnose hawkfish live?
It occupies steep outer reef slopes in the tropical Indian and Pacific Oceans, usually between 10 and 100 meters deep. The fish favors zones with strong water flow and tends to tuck itself among gorgonian sea fans and black corals.
How big does a Longnose hawkfish grow?
Adults reach a maximum total length of about 13 centimeters (5.1 inches), which makes them a modestly sized member of the hawkfish group.
What does a Longnose hawkfish look like?
True to its common name, it has a notably elongated snout and a striking grid-like pattern of red markings over its body. Its dorsal fin is built with 10 spines followed by 13 soft rays.
Is the Longnose hawkfish kept in aquariums?
Yes, the species does show up in the aquarium trade. However, because it naturally lives on deep, current-swept reef slopes among gorgonians, it can be a demanding choice for most home reef tanks.
