Choerodon is a genus of wrasses native to the Indian Ocean and the western Pacific Ocean. [3] They are commonly referred to as tuskfish, because most species have sharp tusk-like teeth.
The genus Choerodon is most closely related to the odacine wrasses. Both groups are part of the wrasse tribe Hypsigenyini. Choerodon is split into 6 subgenera. [4] Molecular phylogenetic analysis has so far demonstrated the monophyly of the subgenera, although not all species in the genus have been evaluated. [5]
Choerodon typus was traditionally placed within its own genus Xiphocheilus, but both morphological and molecular analyses now place it within Choerodon, with Xiphocheilus becoming its subgenus name instead. [4] [5]
Orange-dotted, blue, graphic, and blackspot tuskfish have been recorded using large rocks or hard coral as "anvils", upon which they smash open hard-shelled prey items. All four species belong to the subgenus Choerodon, and can remember to use a particular rock or coral repeatedly for this purpose. This behaviour usually involves invertebrate prey such as clams and sea urchins, but on one occasion, a blue tuskfish was filmed smashing a young green sea turtle on an anvil. [6] [7] [8] [9] [10] Anvil use is also documented in several other wrasse genera. [10] [11] [12]
The 27 currently recognized species in this genus are: [3] [4] [13] [14]

The wrasses are a family, Labridae, of marine ray-finned fish, many of which are brightly colored. The family is large and diverse, with over 600 species in 81 genera, which are divided into nine subgroups or tribes.
The Azurio tuskfish, also known as the scarbreast tuskfin, is a species of wrasse native to the western Pacific, where it occurs off the coasts of eastern Asia. It can be found in areas with rocky substrates at depths from 8 to 50 m. This species can reach a length of 40 cm (16 in). It can be found in the aquarium trade. It is threatened by overfishing and habitat loss; it is a popular target for spearfishers and is considered an excellent food fish.
Scotts' wrasse is a species of wrasse native to the Pacific Ocean, where it occurs at depths of 3 to 40 m on coral reefs from Australia's Great Barrier Reef to the Pitcairn Islands. It can reach a total length of 13 cm (5.1 in). It is found in the aquarium trade.
Jansen's wrasse is a species of ray-finned fish, a wrasse from the family Labridae which is native to the Indian Ocean and Pacific Ocean. In the south-western Pacific Ocean it is replaced by sibling species black-barred wrasse. It can be found in the aquarium trade.
The harlequin tuskfish, Choerodon fasciatus, is a species of wrasse native to the western Pacific Ocean. It occasionally makes its way into the aquarium trade.
The slingjaw wrasse is a species of wrasse from the family Labridae which is native to the tropical waters of the Indo-Pacific where it occurs around coral reefs. This species is of minor importance to local commercial fisheries and can be found in the aquarium trade. This fish is notable for its highly protrusible jaws.
The blackspot tuskfish is a wrasse native to the Indian Ocean and the western Pacific Ocean from Mauritius to Indonesia and Australia north to the Ryukyu Islands. This species occurs on reefs, preferring areas with sandy substrates or areas of weed growth. It can be found at depths from 10 to 60 m, though rarely deeper than 20 m (66 ft). It can reach 100 cm (39 in) in TL, and the greatest published weight for this species is 15.5 kg (34 lb). It is important to local commercial fisheries and is also farmed. It is popular as a game fish, in particular with spearfishers, and can be found in the aquarium trade.
The sixbar wrasse or six-banded wrasse is a species of wrasse in the family Labridae, native to the Indian Ocean and the western Pacific Ocean. It is an inhabitant of reef environments at depths from the surface down to 15 m (50 ft). This species can grow to 20 cm (8 in) in total length, though most individuals do not exceed 15 cm (6 in). It is of minor importance to local commercial fisheries and can also be found in the aquarium trade.
Gerald Robert "Gerry" Allen is an American-born Australian ichthyologist. His career began in 1963, when he spent a semester at the University of Hawaii, where he also received a PhD in marine zoology in 1971. In 1972, Allen wrote his doctoral thesis on the systematics and biology of the anemone fish.
The orange-dotted tuskfish is a species of wrasse native to the Indian Ocean from Sri Lanka eastward to French Polynesia in the western Pacific. Its range extends north to the Ryukyus and south to New Caledonia. It inhabits reefs at depths from 1 to 25 m (3.3–82.0 ft). This species can reach a length of 50 cm (20 in). It is commercially important, and can be found in the aquarium trade.
Abudefduf troschelii, the Pacific sergeant major or Panama sergeant major, is a species of damselfish belonging to the family Pomacentridae that can be identified by the pronounced black stripes on the lateral sides of the fish. Its specific name honors the zoologist Franz Hermann Troschel (1810-1882). It is native to the neritic pelagic zone of the shallow water coral reefs in the Eastern Pacific Ocean and they are an omnivorous species feeding on plankton and algae attached to their coral habitat. Abudefduf troschelii is a sister-species of A. saxatilis but have diverged from each other since the uplift of the isthmus of Panama, separated by the rise of the Panama land bridge 3.1 to 3.5 million years ago. Males, like in many other marine species, take care of and defend newborn A. troschelii after they have been hatched by eggs from the female. There are currently no major threats to the species and there is no indication of a current decline in its population size. The IUCN Red List lists this damselfish as being of “least concern”.
Chlorurus troschelii, commonly known as Troschel's parrotfish, is a species of marine ray-finned fish, a parrotfish from the family Scaridae. It is native to the eastern Indian Ocean, where it lives in coral reefs.
The blackear wrasse is a species of wrasse, a type of fish in the family Labridae, from the warmer waters of the western Atlantic Ocean.
Halichoeres burekae, the Mardi Gras wrasse, is a species of wrasse native to the Gulf of Mexico. The species was first described from the Flower Garden Banks National Marine Sanctuary, in the northwestern Gulf of Mexico, but has since been recorded in other areas of the southern Gulf of Mexico. Because it is a small species that feeds on plankton in the water column, it is likely a preferred prey for invasive Lionfish. It also has a very restricted range, and corresponding relatively small population, what resulted in this species being listed as Endangered in the IUCN Red List.
Cirrhilabrus condei are fairy wrasse which is also known as Conde's wrasse. They originate from the shallow rubble flats of Melanesia. The Conde's fairy wrasse is very peaceful; they are red alone black with a white belly. Female Conde's wrasse are red with a pale stripe along the lower rear, a black dorsal fin, a pale stripe with a white lower body, and a red anal fin. Males are similar with more intense coloration. The life cycle and mating behavior of Cirrhilabrus condei distinct pairing during breeding. Unlike other wrasses, they raise the front 2/3 of their dorsal fins and sometimes colors may vary depending on the fish's mood, breeding timeframe, and age of the specimen.
Xyrichtys rajagopalani, the Rajagopalan's razorfish, is a species of marine ray-finned fish from the family Labridae, the wrasses. It is found in the Indian Ocean.
Anampses cuvier, the pearl wrasse, is a species of fish found in the Pacific Ocean.
Halichoeres hartzfeldii, also known as Hartzfeld's wrasse, is a species of salt water wrasse found in the western Pacific Ocean.
Bodianus perditio, the golden-spot hogfish, is a species of wrasse found in the Pacific Ocean.
Bodianus masudai is a species of wrasse. It is found in the western Pacific Ocean.
