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.

Contents

Taxonomy

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]

Potential tool use in tuskfishes

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]

<i>Abudefduf troschelii</i> Species of fish

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”.

<i>Chlorurus troschelii</i> Species of fish

<i>Halichoeres burekae</i> Species of fish

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.
