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.
Cichlids are fish from the family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses (Labridae), in the order Perciformes, but molecular studies have contradicted this grouping. The closest living relative of cichlids is probably the convict blenny, and both families are classified in the 5th edition of Fishes of the World as the two families in the Cichliformes, part of the subseries Ovalentaria. This family is both large and diverse. At least 1,650 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000.
FishBase is a global species database of fish species. It is the largest and most extensively accessed online database on adult finfish on the web. Over time it has "evolved into a dynamic and versatile ecological tool" that is widely cited in scholarly publications.
Ophidiiformes is an order of ray-finned fish that includes the cusk-eels, pearlfishes, viviparous brotulas, and others. Members of this order have small heads and long slender bodies. They have either smooth scales or no scales, a long dorsal fin and an anal fin that typically runs into the caudal fin. They mostly come from the tropics and subtropics, and live in both freshwater and marine habitats, including abyssal depths. They have adopted a range of feeding methods and lifestyles, including parasitism. The majority are egg-laying, but some are viviparous.
Pearlfish are marine fish in the ray-finned fish family Carapidae. Pearlfishes inhabit the tropical waters of the Atlantic, Indian, and Pacific Oceans at depths to 2,000 m (6,600 ft), along oceanic shelves and slopes. They are slender, elongated fish with no scales, translucent bodies, and dorsal fin rays which are shorter than their anal fin rays. Adults of most species live symbiotically inside various invertebrate hosts, and some live parasitically inside sea cucumbers. The larvae are free living.
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Around 99% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with over 95% belonging to the teleost subgrouping.
The ring-tailed cardinalfish is a widespread fish species in the family Apogonidae found in the Red Sea and off East Africa to Papua New Guinea, north to Japan, and south to Australia.
The worm pearlfish is an eel-like fish in the family Carapidae.
Rainer Froese is a senior scientist at the Helmholtz Center for Ocean Research (GEOMAR) in Kiel, formerly the Leibniz Institute of Marine Sciences (IFM-GEOMAR), and a Pew Fellow in Marine Conservation. He obtained an MSc in Biology in 1985 at the University of Kiel and a PhD in Biology in 1990 from the University of Hamburg. Early in his career, he worked at the Institute of Marine Sciences on computer-aided identification systems and the life strategies of fish larvae. His current research interests include fish information systems, marine biodiversity, marine biogeography, and the population dynamics of fisheries and large marine ecosystems.
Echiodon is a genus of pearlfishes, with these currently recognized species:
Onuxodon is an Indo-Pacific genus of pearlfishes from the family Carapidae. The generic name is derived from the Greek onyx meaning "claw" and odon meaning "tooth", referring to the sharp fang like teeth of Onuxodon parvibrachium. Species in this genus are distributed from South Africa to Hawaii. They live commensally with molluscs. The three currently recognized species are:
Alcockia is a genus in the cusk-eel family. It contains only the single species Alcockia rostrata, which is found in the Indian and western Pacific Oceans, at depths of from 2,761 to 4,040 metres. This species grows to a length of 35 centimetres (14 in) SL. The generic name Alcockia honours Alfred William Alcock (1859-1933) who was the surgeon-naturalist aboard the R.I.M.S. Investigator.
Tauredophidium hextii is a species of cusk-eel found in the Indian and western Pacific Oceans. It occurs at depths of from 1,500 to 2,660 metres. This species grows to a length of 10.5 centimetres (4.1 in) SL. It is the only known member of its genus. The specific name honours Rear-Admiral John Hext (1842-1924) who was commander of the Royal Indian Marine who supported the expedition in board the R.I.M.S. Investigator in the Arabian Sea which collected the type specimen.
The East Pacific ventbrotula is a species of cusk-eel found around thermal vents on the southern East Pacific Rise at depths of about 2,586 metres (8,484 ft). This species grows to a length of 28.2 centimetres (11.1 in) SL. It is the only known member of its genus. The generic name is a compound of vent, for the Oasis hydrothermal vent on the south East Pacific Rise and the Greek ichthys meaning "fish", while the specific name refers to the French BIOSPEEDO expedition to the south East Pacific Rise which collected the type specimen in 2004.
Roche's snake blenny is a fish species in the genus Ophidion and the family Ophidiidae. Widespread in the Mediterranean Sea in western and northern regions, also in the Black Sea, Sea of Marmara and it has been recorded in the Atlantic. Marine subtropical demersal fish, up to 29.3 centimetres (11.5 in) long. This fish species has distinctive sonic capabilities, produced by the dorsal, intermediate, and ventral sonic muscles. Additionally, females tend to produce sounds having short duration and pulsation, while male sounds are longer and show a unique pattern of pulsation, resulting in characteristic distinctions between the Ophidion rochei and the Ophidion barbatum, its twin species. The specific name honors the Swiss physician and naturalist François-Etienne Delaroche (1780-1813), who wrote about the distinctive swim-bladder anatomy of Ophidion barbatum in 1809.
Holothuria leucospilota, commonly known as the black sea cucumber or black tarzan, is a species of marine invertebrate in the family Holothuriidae. It is placed in the subgenus Mertensiothuria making its full scientific name Holothuria (Mertensiothuria) leucospilota. It is the type species of the subgenus and is found on the seabed in shallow water in the Indo-Pacific.
The pinhead pearlfish, Encheliophis boraborensis, is a species of slender, ray-finned fish in the family Carapidae found in the tropical Indo-Pacific Ocean; it normally lives inside the body cavity of a sea cucumber such as the pineapple sea cucumber or the leopard sea cucumber.
The silver pearlfish, Encheliophis homei, is a species of eel-like fish in the family Carapidae. This pearlfish lives inside the coelom of sea cucumbers such as Bohadschia argus, Thelenota ananas , and Stichopus chloronotus. It is native to tropical and subtropical parts of the Indo-Pacific Ocean.
Echiodon anchipterus, the Closefin pearlfish, is a fish species described by Jeffrey T. Williams in 1984. Echiodon anchipterus is part of the genus Echiodon and the subfamily Carapinae. No subspecies are listed in the Catalog of Life.
