The black-barred wrasse (Thalassoma nigrofasciatum) is a species of ray-finned fish, a wrasse from the family Labridae which is native to the southwestern Pacific Ocean.
In the black-barred wrasse the adults are blackish above and have the ventral half of the head, chest and belly white. There is a short white to yellow vertical stripe which starts above the pectoral-fin base, a further two broad white to yellow stripes are on the flanks and they have a yellow tail. In females, the pale areas are largely white, while in the males the pale areas are more yellow. The males also have a pale pink chin and long, thin filaments on the lobes of the caudal fin [2] and pink patches on the ventral parts of the head and chest. Males have been measured at standard length of 20 centimetres (7.9 in). [3] This species is frequently confused with the similar Jansen's wrasse (Thalassoma janseni). [2]
The black-barred wrasse is found in the south western Pacific Ocean from eastern Papua New Guinea and the Solomon Islands south to the Great Barrier Reef, Lord Howe Island and Norfolk Island, the Kermadec Islands, New Caledonia and Tonga, it has also been recorded in Niue. [1]
The black-barred wrasse occurs in tidal pools and reefs, both inner and outer reefs, between 0 to 15 metres (0 to 49 ft). [1] It can occur solitarily or in small groups. [2]
The black-barred wrasse was only described in 2003, it is closely related to Jansen's wrasse and the two species may be easily confused. Many of their molecular characteristics are the same but they do differ in a single nucleotide of the cytochrome b sequence. Despite being morphologicallu almost identical, they are each most probably separate and valid species and there may have been confusion over identification in previously stated distributions. [1]
Thalassoma bifasciatum, the bluehead, bluehead wrasse or blue-headed wrasse, is a species of marine ray-finned fish, a wrasse from the family Labridae. It is native to the coral reefs of the tropical waters of the western Atlantic Ocean. Individuals are small and rarely live longer than two years. They form large schools over the reef and are important cleaner fish in the reefs they inhabit.
Thalassoma is a genus of wrasses native to the Atlantic, Indian and Pacific Oceans. Many species occasionally make their way into the aquarium trade.
The moon wrasse also known as the crescent wrasse or lyretail wrasse, is a species of wrasse native to the Indian Ocean and the western Pacific Ocean. It is an inhabitant of coral reefs and surrounding areas at depths from 1 to 20 m. Moon wrasses are carnivorous and tend to prey on fish eggs and small sea-floor dwelling invertebrates. This species can reach 45 cm (18 in) in total length. It is of minor importance to local commercial fisheries and can also be found in the aquarium trade.
The slippery dick is a species of wrasse native to shallow, tropical waters of the western Atlantic Ocean.
The Christmas wrasse, also known as the ladder wrasse, green-barred wrasse or green-blocked wrasse, is a species of ray-finned fish, a wrasse from the family Labridae which is native to the Indian Ocean and the western Pacific Ocean. It inhabits shallow reefs at depths from the surface to 10 m (33 ft). It is of minor importance to local commercial fisheries and can be found in the aquarium trade.
The exquisite wrasse is a species of ray-finned fish from the family Labridae, the wrasses, which is native to reefs in the Indo-West Pacific region. It can be 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 fivestripe wrasse, also known as the red-ribbon wrasse, is a species of marine ray-finned fish, a wrasse, from the family Labridae. It is found in the Indo-Pacific region.
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. Relatively mundane at first glance, this fish is notable for its highly protrusible jaws.
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.
The surge wrasse, also known as the green-blocked wrasse, purple wrasse or red and green wrasse, is a species of wrasse native to the southeast Atlantic Ocean through the Indian and Pacific Oceans, where it inhabits reefs and rocky coastlines in areas of heavy wave action at depths from the surface to 10 m (33 ft). This species is of minor importance to local commercial fisheries, is popular as a game fish, and can be found in the aquarium trade.
The barred thicklip wrasse is a species of fish belonging to the wrasse family, native from the Indo-Pacific.
The chiseltooth wrasse is a species of marine ray-finned fish, a wrasse from the family Labridae. It is native to the Indian Ocean and the western Pacific Ocean. It is an inhabitant of coral reefs and can be found at depths from 3 to 60 m, though rarely deeper than 40 m (130 ft). This species grows to 30 cm (12 in) in total length. It is of minor importance to local commercial fisheries and can be found in the aquarium trade. P. moluccanus is the only known member of its genus.
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”.
Genicanthus melanospilos, the spotbreast angelfish, blackspot angelfish or swallowtail angelfish, the family Pomacanthidae. It occurs in the Indo-West Pacific region.
