The oceanic whitetip shark is a large pelagic requiem shark inhabiting tropical and warm temperate seas. It has a stocky body with long, white-tipped, rounded fins. The species is typically solitary, though they may gather in large numbers at food concentrations. Bony fish and cephalopods are the main components of its diet and females give live birth.
Pangio is a genus of small Asian freshwater fish in the true loach family Cobitidae. In earlier taxonomic schemes it was known as Acanthophthalmus. The "kuhli loach" is well-known in the aquarium trade and commonly identified as P. kuhlii, but most individuals actually appear to be P. semicincta.
The New Zealand longfin eel, also known as ōrea, is a species of freshwater eel that is endemic to New Zealand. It is the largest freshwater eel in New Zealand and the only endemic species – the other eels found in New Zealand are the native shortfin eel, also found in Australia, and the naturally introduced Australian longfin eel. Longfin eels are long-lived, migrating to the Pacific Ocean near Tonga to breed at the end of their lives. They are good climbers as juveniles and so are found in streams and lakes a long way inland. An important traditional food source for Māori, who name them ōrea, longfin eel numbers are declining and they are classified as endangered, but over one hundred tonnes are still commercially fished each year.
The mottled eel, also known as the African mottled eel, the Indian longfin eel, the Indian mottled eel, the long-finned eel or the river eel, is a demersal, catadromous eel in the family Anguillidae. It was described by John McClelland in 1844. It is a tropical, freshwater eel which is known from East Africa, Bangladesh, Andaman Islands, Mozambique, Malawi, Sri Lanka, Sumatra, and Indonesia and recently from Madagascar. The eels spend most of their lives in freshwater at a depth range of 3–10 metres, but migrate to the Indian Ocean to breed. Males can reach a maximum total length of 121 centimetres and a maximum weight of 7,000 grams. The eels feed primarily off of benthic crustaceans, mollusks, finfish and worms.
The pink maomao, also known as the longfin perch, is a species of marine ray-finned fish, a member of the subfamily Anthiinae which is part of the grouper and sea bass family Serranidae. It is found in the southern Pacific and the southeastern Indian Ocean.
The speckled moray eel is a moray eel found in the eastern Pacific Ocean, around the Galapagos Islands and along the Central American coast from Costa Rica to Colombia. It is also found in the Gulf of California. It reaches a length of about 170 cm.
The Pacific hagfish is a species of hagfish. It lives in the mesopelagic to abyssal Pacific ocean, near the ocean floor. It is a jawless fish and has a body plan that resembles early paleozoic fish. They are able to excrete prodigious amounts of slime in self-defense.
Mastacembelus is a genus of many species of spiny eel fish from the family Mastacembelidae. They are native to Africa and Asia. Most are found in rivers and associated systems, but there are also species in other freshwater habitats and a particularly rich radiation is found in the Lake Tanganyika basin with 15 species. A few species can even occur in brackish water.
Monopenchelys acuta, the redface moray or redface eel, is a species of saltwater eel, the only member of the genus Monopenchelys of the Muraenidae family. It is found in the Atlantic, the eastern Pacific, and the western Indian Ocean. Its length is up to 209 mm (8.2 in).
The wolf eel is a species of marine ray-finned fish belonging to the family Anarhichadidae, the wolf fishes. It is found in the North Pacific Ocean. Despite its common name and resemblance, it is not a true eel. It is the only species in the monotypic genus Anarrhichthys.
Lethrinops longimanus is a species of cichlid endemic to Lake Malawi where it is found in deep waters 50 to 70 metres over sandy substrates. This species grows to a length of 15.3 centimetres (6.0 in) SL.
Placidochromis longimanus is a species of cichlid native to the southern portion of Lake Malawi, Lake Malombe and the Shire River. It is believed to only be found in areas vegetated with Ceratophyllum and Najas at approximately 10 metres (33 ft) in depth. This species can reach a length of 14.5 centimetres (5.7 in) TL. It is also important to local commercial fisheries as well as being found in the aquarium trade. It is the type species of the genus Placidochromis.
Eels are ray-finned fish belonging to the order Anguilliformes, which consists of eight suborders, 20 families, 164 genera, and about 1000 species. Eels undergo considerable development from the early larval stage to the eventual adult stage and are usually predators.
Mastacembelus ellipsifer is a species of spiny eel that is endemic to Lake Tanganyika in Africa and sometimes kept in aquariums. Although sometimes called the Tanganyikan spiny eel, it is only one of fifteen spiny eel species in the Tanganyikan basin.
Eels are elongated fish, ranging in length from five centimetres (2 in) to four metres (13 ft). Adults range in weight from 30 grams to over 25 kilograms. They possess no pelvic fins, and many species also lack pectoral fins. The dorsal and anal fins are fused with the caudal or tail fin, forming a single ribbon running along much of the length of the animal. Most eels live in the shallow waters of the ocean and burrow into sand, mud, or amongst rocks. A majority of eel species are nocturnal and thus are rarely seen. Sometimes, they are seen living together in holes, or "eel pits". Some species of eels live in deeper water on the continental shelves and over the slopes deep as 4,000 metres (13,000 ft). Only members of the family Anguillidae regularly inhabit fresh water, but they too return to the sea to breed.
Taylor's garden-eel is a heteroconger belonging to the family Congridae. It is native to the central Indo-Pacific.
The longfin mojarra is a species of mojarra native to the coastal waters of the Indian Ocean from India to the western Pacific. This species grows to 15 cm (5.9 in) in total length, though most do not exceed 10 cm (3.9 in). This species is of minor importance to local commercial fisheries, usually being made into fish meal or feed for ducks. It is the only known member of the genus Pentaprion.
The Mekong flying barb is a species of cyprinid found in Mekong river basins in Thailand, Laos, Cambodia and Viet Nam.
