Altrichthys is a small genus of damselfish in the family Pomacentridae, native to the central Indo-Pacific. [1]
There are three species in the genus. [1] [2]
Mackerel is a common name applied to a number of different species of pelagic fish, mostly from the family Scombridae. They are found in both temperate and tropical seas, mostly living along the coast or offshore in the oceanic environment.
The New Zealand demoiselle, Chromis dispilus, is a damselfish of the genus Chromis, found between North Cape and East Cape of the North Island of New Zealand to depths of about 60 metres, off rocky coasts. Its length is between 15 and 20 cm. Males are highly territorial as they defend their nesting area from other males and other species. These aggressive fish defend their eggs laid by their female counterpart. Spawning occurs between the months of December and March. The New Zealand demoiselle's territory and nesting grounds of this fish are usually the largest in a medium population density. Like most territorial fish they tend to spawn more in higher densities of the same species compared to lower densities. Aggression levels tend to be higher amount higher densities of the same species and lower levels in smaller densities. Aggression also tends to be higher during spawning then during egg defending. Elevated plasma levels of androgen testosterone and 11-Ketotesterone are associated with the heighten levels of aggression shown by the males.
The one-spot puller or brown puller, Chromis hypsilepis, is a damselfish of the genus Chromis, found off south-east Australia and between North Cape and East Cape of the North Island of New Zealand to depths of about 60 metres, off rocky coasts. It grows to a length between 15 and 20 centimetres.
Amblyglyphidodon is a genus of fish in the family Pomacentridae. These damselfish swim singly, in pairs, or in small groups. They are often found among corals.
Amblypomacentrus is a small genus of fish in the family Pomacentridae. As of the year 2000, there are 3 species.
Stegastes 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.
Chrysiptera cyanea is a species of damselfish found in the wide Indo-West Pacific but not known in the Red Sea. A few individuals were observed in the Mediterranean Sea in 2013 off Slovenia, a likely aquarium release.
Fish are very diverse animals and can be categorised in many ways. Although most fish species have probably been discovered and described, about 250 new ones are still discovered every year. According to FishBase about 34,800 species of fish had been described as of February 2022, which is more than the combined total of all other vertebrate species: mammals, amphibians, reptiles and birds.
Several species of fish are claimed to produce hallucinogenic effects when consumed. For example, Sarpa salpa, a species of sea bream, is commonly claimed to be hallucinogenic. These widely distributed coastal fish are normally found in the Mediterranean and around Spain, and along the west and south coasts of Africa. Occasionally they are found in British waters. They may induce hallucinogenic effects similar to LSD if eaten. However, based on the reports of exposure they are more likely to resemble hallucinogenic effects of deliriants than the effects of serotonergic psychedelics such as LSD. In 2006, two men who apparently ate the fish experienced hallucinations lasting for several days. The likelihood of hallucinations depends on the season. Sarpa salpa is known as "the fish that makes dreams" in Arabic.
Plectroglyphidodon johnstonianus, commonly known as the Johnstone Island damselfish, is a species of damselfish from the Indo-Pacific. It occasionally makes its way into the aquarium trade. It grows to a size of 14 cm in length.
Amblyglyphidodon curacao; also known as the staghorn damselfish , the clouded damselfish or the bare-snouted sergeant major; is a species of marine fish in the family Pomacentridae, the damselfishes and the clownfishes. It's widespread throughout the tropical waters of the western Pacific Ocean. This species is a small sized fish that can reach a maximum size of 11 cm length.
The immaculate damselfish, also known as the green puller, is a species of ray-finned fish, it is the only species in the monotypic genus Mecaenichthys, classified in the subfamily Pomacentrinae of the family Pomacentridae.
The big-lip damselfish is a species of ray-finned fish from the family Pomacentridae, it is the only species in the monotypic genus Cheiloprion. It occurs in the eastern Indian Ocean and south western Pacific Ocean and has been recorded from Sri Lanka east to the Solomon Islands, north to the Philippines, south to Vanuatu as well as northern Australia, from Shark Bay in Western Australia to Palm Island, Queensland. and Palau.
Pomacentrus philippinus, the Philippine damsel, is a damselfish species described by Barton Warren Evermann and Alvin Seale in 1907. Pomacentrus philippinus is part of the genus Pomacentrus and the family Pomacentridae.
Pomacentrus littoralis, the Smoky damselfish is a damselfish species described by Georges Cuvier in 1830. Pomacentrus littoralis is part of the genus Pomacentrus and the family Pomacentridae.
Pomacentrus grammorhynchus, the Bluespot damselfish, is a damselfish species described by Henry Weed Fowler in 1918. Pomacentrus grammorhynchus is part of the genus Pomacentrus and the family Pomacentridae.
Pycnochromis atripes, the dark-fin chromis, is a diurnal species of damselfish belonging to the genus Pycnochromis. It can be found in the Western Pacific Ocean in Christmas Islands and in north-western Australia in the East Indian Ocean to Kiribati, and north to Southern Japan. It can also be found in Tonga. It inhabits areas of outer reef and slopes which are rich in coral, appearing singly or in small groups near the bottom. It is oviparous, and the males of the species guard and aerate the eggs.>
Pycnochromis delta, the deep reef chromis, is a diurnal species of damselfish belonging to the genus Chromis. It can be found in the Indo-West Pacific, from Maldives and Christmas Island to Fiji, north to Taiwan and the Philippines, and south to Vanuatu. It can also be found in Tonga. It inhabits steep outer reef slopes with rich coral growth. They can either appear singly or in small groups remaining near shelter, often at the entrance of large caves or near its ceiling. It is oviparous, and the males of the species guard and aerate the eggs.
