Stegastes marginatus, commonly called the Hawaiian gregory, is a species of damselfish in the family Pomacentridae that is endemic to the Hawaiian Islands. It feeds on filamentous algae.
Stegastes marginatus is endemic to Hawaii, where it is found on shallow seaward reefs particularly in areas with mild to moderate water movement. Although previously synonymized with S. fasciolatus , it is apparently distinct based on DNA and morphological study. [1]
The Northwestern Hawaiian Islands also known as the Leeward Hawaiian Islands, are a series of islands and atolls located northwest of Kauai and Niʻihau in the Hawaiian island chain. Politically, these islands are part of Honolulu County in the U.S. state of Hawaii, with the exception of Midway Atoll. Midway Atoll is a territory distinct from the State of Hawaii, and is classified as one of the United States Minor Outlying Islands. The United States Census Bureau designates this area, excluding Midway Atoll, as Census Tract 114.98 of Honolulu County. The total land area of these islands is 3.1075 square miles. With the exception of Nihoa, all these islands lie north of the Tropic of Cancer, making them the only islands in Hawaii situated outside the tropics.
Stegastes, commonly known as Gregories, is a genus of ray-finned fish in the family Pomacentridae. Members of this genus are marine coastal fishes except for S. otophorus, which also occurs in brackish water. These fish are known by the names of damselfish, gregory and major. They are small tropical fish associated with coral and rocky reefs in the Atlantic, Indian and Pacific Oceans. They are sometimes found in the aquarium trade where they are an easy-to-keep fish, but they do not mix well with other fish of their own or other species because of their territorial habits and aggressiveness.
Dascyllus marginatus is a damselfish endemic to the Western Indian Ocean. It is a site attached fish that lives in corals, usually Stylophora pistillata and species of Acropora. In these corals it hides at a moment of danger and sleeps at night. It feeds on zooplankton that drifts with the current, and grows to a size of 6 cm in length. Dascyllus marginatus lives in groups of 2-25 individuals, and while foraging for food around their home coral, group members keep separated and stable foraging spaces.
Stegastes planifrons is a damselfish from the Western Atlantic. It occasionally makes its way into the aquarium trade.
Panulirus marginatus, the Hawaiian spiny lobster, is a species of spiny lobster in the family Palinuridae which is endemic to the Hawaiian Islands. It is the subject of extensive commercial and recreational fisheries.
Stegastes adustus, also known as the dusky damselfish or scarlet-backed demoiselle, is a species of damselfish in the family Pomacentridae. It is found at one- to three-meter depths on surging and wavy coral reefs in the Caribbean Sea, the tropical waters of the western Atlantic Ocean, and the Gulf of Mexico.
Stegastes pictus, the yellowtip damselfish, is a species of damselfish found near the sea bed on shallow rocky reefs off the coast of Brazil, where it is endemic. It is a small, laterally-compressed, dark brown fish with yellow pectoral and caudal fins. It feeds on algae and detritus and is often found in the vicinity of the fire coral Millepora alcicornis. It is a territorial fish and forms a pair bond in the breeding season. The eggs are laid in a shallow scoop on the seabed and the male tends them to keep them well-aerated.
Stegastes albifasciatus, known commonly as the whitebar gregory or white-banded gregory, is a damselfish of the family Pomacentridae native to the western Indo-Pacific. Its range extends from the Seychelles and Réunion to the Ryukyu Islands, the Tuamoto Islands, and New Caledonia, where it is found on reef flats, reef margins and lagoons on patches of rubble or reef rock with live corals, particularly in areas of moderate water movement.
Stegastes apicalis, commonly known as the Australian gregory or yellowtip gregory, is a damselfish of the family Pomacentridae. It is native to the Western Pacific where it occurs on the east coast of Australia, the Great Barrier Reef, Queensland and New South Wales. It has also been reported from Taiwan and Ouvéa Island in the Loyalty Islands.
Stegastes fasciolatus, commonly called the Pacific gregory, is a species of damselfish in the family Pomacentridae. It is native to the tropical western Indo-Pacific. It feeds on filamentous algae.
Stegastes leucorus, commonly known as the whitetail damselfish, the whitetail gregory or the whitetail major, is a damselfish of the family Pomacentridae. It is native to the tropical eastern Pacific Ocean.
Stegastes acapulcoensis, commonly called the Acapulco major, the Acapulco damselfish, or the Acapulco gregory, is a species of damselfish of the family Pomacentridae. It is native to the eastern Pacific Ocean.
Stegastes apicalis, commonly known as the Japanese gregory, is a damselfish of the family Pomacentridae.
Stegastes arcifrons, the island major or Galapagos gregory, is a damselfish of the family Pomacentridae native to the eastern Pacific Ocean. Its range extending from Costa Rica to the Cocos Islands, Malpelo Island, and the Galapagos Islands. It is found on rocky and coral reefs at depths ranging from 1 to 20 m. It is common in many parts of its range, and its population appears to be stable. No particular threats have been identified, and the IUCN rates it as being of "Least Concern".
Stegastes aureus, the golden gregory, is a damselfish of the family Pomacentridae native to islands in the tropical Pacific Ocean, its range including New Caledonia, the Gilbert Islands, Line Island, Phoenix Island, Samoa, the Tuamotu Archipelago, and the Marquesas Islands. It is found on coral reefs at depths ranging from 1 to 5 m.
Stegastes flavilatus, commonly known as beaubrummel, is a damselfish of the family Pomacentridae. It is native to the tropical eastern Pacific Ocean, its range extends from Mexico, Baja California and the Gulf of California southwards to the Galapagos Islands and mainland Ecuador. It is found on rocky inshore reefs at depths ranging from 1 to 10 m.
Stegastes redemptus, commonly known as the clarion major, clarion damselfish or clarion gregory, is a damselfish of the family Pomacentridae. It is native to the tropical eastern Pacific Ocean, its range extending from the Revillagigedo Islands to the coast of Baja California. It is found on rocky reefs at depths ranging from 1 to 15 m.
Stegastes pelicieri, commonly known as the Mauritian gregory, is a damselfish of the family Pomacentridae. It is native to the islands of Mauritius and Réunion in the western Indian Ocean where it is found at depths between two and twenty metres. It lives on rocky reefs in areas with little coral but plenty of holes and crevices.
