The novaculine wrasses are saltwater fish of the tribe Novaculini, a subgroup of the wrasse family (Labridae). The group is also known more colloquially as the razorfishes. They are found throughout the global tropics, and live obligately on the sand plains of reef-associated slopes. [1]
There is some uncertainty as to whether the novaculine wrasses are the sister group to the cigar wrasse (Cheilio inermis) or to the Juan Fernández wrasse ( Malapterus reticulatus ). Molecular phylogenetics consistently finds Novaculichthys to be the sister group to the rest of the tribe. [1] [2]
Taxonomy of the group has traditionally been hindered by the problem that outwardly, some species can only be distinguished from each other by their colour patterns, which often do not persist in preserved specimens. Moreover in live specimens, males, females, and juveniles within the same species can vary greatly in appearance, and it is unknown what some of these growth stages look like in certain species. [3] This has become less of a problem with the advent of molecular phylogenetics, [2] but even so, these fish are difficult to find, and even more difficult to capture, limiting the study of this unusual group of wrasses. [3]
The novaculine wrasses live on sandbeds, usually associated with reefs. Their common name "razorfish" is derived from their flattened, blade-like snouts and strongly laterally compressed bodies. These adaptations allow them to dive into and move quickly through sand. [3] [4]
Females can change sex into males. Most species form harems. The larval form is relatively long lived, lasting up to several months, and can be found in the open ocean. [3]

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.
Parrotfish are a group of fish species traditionally regarded as a family (Scaridae), but now often treated as a subfamily (Scarinae) or tribe (Scarini) of the wrasses (Labridae). With roughly 95 species, this group's largest species richness is in the Indo-Pacific. They are found in coral reefs, rocky coasts, and seagrass beds, and can play a significant role in bioerosion.
Choerodon is a genus of wrasses native to the Indian Ocean and the western Pacific Ocean. They are commonly referred to as tuskfish, because most species have sharp tusk-like teeth.
The checkerboard wrasse is a fish belonging to the wrasse family. It is native to the area including the Indian Ocean to central Pacific Ocean.
The bird wrasse, Gomphosus varius, is a species of the wrasse family.
The barred thicklip wrasse is a species of fish belonging to the wrasse family, native from the Indo-Pacific.
The yellow-breasted wrasse, Anampses twistii, is a species of wrasse native to the tropical waters of the Indo-Pacific area from the Red Sea to the Tuamoto Islands. It is found in lagoons and on reefs at depths of 5 to 30 m. It can reach a length of 18 cm (7.1 in). It is of minor importance to local commercial fisheries and can be found in the aquarium trade.
The blue-banded wrasse is a species of wrasse native to the easternmost Indian Ocean and the western Pacific Ocean. It is an inhabitant of reefs, preferring substrates of flat sand or rubble at depths of from 15 to 85 m. This species grows to 12 cm (4.7 in) in standard length. It is of minor importance to local commercial fisheries.
The blackeye thicklip wrasse or half-and-half wrasse is a species of fish belonging to the wrasse family. It is native to the Indo-Pacific.
Iniistius pentadactylus, the fivefinger wrasse or fivefinger razorfish, is a species of marine ray-finned fish from the family Labridae, the wrasses, which has a wide Indo-Pacific distribution.
Halichoeres prosopeion, commonly called the twotone wrasse, half-grey wrasse or zig-zag wrasse, is a fish species in the wrasse family native to the western Pacific Ocean.
Labriformes is an order of ray-finned fishes which includes the wrasses, cales and parrotfishes, within the clade Percomorpha. Some authors include the Labriformes as the clade Labroidei within the Perciformes while others include more families within the Labriformes, such as the cichlids and damselfishes, but the 5th edition of Fishes of the World includes just three listed in the section below and includes 87 genera and about 630 species.
Pseudolabrus guentheri, or Gunther's wrasse, is a ray-finned fish from the wrasse family. It was named for Albert Günther.
Cirrhilabrus finifenmaa, also known by its common name rose-veiled fairy wrasse, is a rainbow-colored wrasse that is native to the reefs of the Maldives.
Iniistius celebicus, the Celebes razorfish, is a species of marine ray-finned fish in the family Labridae, the wrasses. It is found in the Pacific Ocean.
Anampses neoguinaicus, also known as the New Guinea wrasse and black-banded wrasse, is a species of fish found in the western Pacific Ocean.
Anampses geographicus, the geographic wrasse, is a species of fish found in the Indo-West Pacific Ocean.
The julidine wrasses are saltwater fish of the tribe Julidini, a subgroup of the wrasse family (Labridae). It contains the highest number of genera and species out of all the wrasse tribes, with 20 genera and over 200 species, comprising almost a third of all wrasse species.
The cheiline wrasses are saltwater fish of the tribe Cheilinini, a subgroup of the wrasse family (Labridae).
The hypsigenyine wrasses are saltwater fish of the tribe Hypsigenyini, a subgroup of the wrasse family (Labridae). The group is circumglobal, being found in almost all the of world's shallow tropical marine waters, although some species are also found in temperate zones.
