Abudefduf, also known as the sergeant-majors, is a genus of fish in the family Pomacentridae.
The Indo-Pacific sergeant is a species of damselfish in the family Pomacentridae. It may also be known as the Sergeant major although this name is usually reserved for the closely related species Abudefduf saxatilis. The closely related Abudefduf caudobimaculatus was formerly considered to be synonymous with this species and, according to some authorities, is synonymous.
The green damselfish, also known as the Hawaiian sergeant major, is a non-migratory fish of the family Pomacentridae. This fish also goes by the name maomao It occurs in the Pacific Ocean in the vicinity of the Hawaiian Islands, Midway Island and Johnston Atoll. It can grow to a maximum total length of 30 centimetres (12 in).
Rhinopias eschmeyeri or Eschmeyer's scorpionfish or mauritius scorpionfish, is a species of marine ray-finned fish belonging to the family Scorpaenidae, the scorpionfishes. This species is found in the Indo-West Pacific. It grows to an average size of 16.6 cm in length. It occasionally makes its way into the aquarium trade. Although some have raised questions as to whether R. eschmeyeri is a morphological variant of Rhinopias frondosa rather than a separate species, a 2006 study by Motomura and Johnson confirmed the species' existence and distinguished it from other members of the genus Rhinopias. It is sometimes confused with the leaf scorpionfish.
The barchin scorpionfish is a species of marine ray-finned fish belonging to the family Scorpaenidae, the scorpionfishes. It comes from the Indo-Pacific. The species is commonly seen in areas with mixed sand and rubble in reef flats, shallow lagoons, and channels.
The dusky sergeant, also known as the night sergeant, is a species of damselfish in the family Pomacentridae endemic to the eastern Pacific Ocean. The species can reach 19 cm (7.5 in) in total length.
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”.
The yellowtail sergeant is a species of damselfish in the family Pomacentridae native to the Indo-Pacific. It can grow to a maximum total length of 17 centimetres (6.7 in).
Amblyglyphidodon flavilatus, known as yellow damselfish, yellowfin damselfish, yellow flank damselfish, yellow side damselfish, and yellow-sided Damselfish, is part Pomacentridae, which is a family of ray-finned fish including damselfish and clownfish. This family represents the greatest diversity and abundance of fish species inhabiting coral reefs. They were first described in 1980 by Allen and Randall.
