Chelon Tricuspidens
''Chelon tricuspidens'', the striped mullet, is a species of ray-finned fish from the family Mugilidae. It is found in southern Africa where its known range comprises Mossel Bay Mossel Bay ( af, Mosselbaai) is a harbour town of about 99,000 people on the Southern Cape (or Garden Route) of South Africa. It is an important tourism and farming region of the Western Cape Province. Mossel Bay lies 400 kilometres east of the ... and the Kosi Estuary in South Africa. Its habitatis muddy areas in estuaries. This species and the Diassanga mullet (''Chelon bandialensis'') are closely related and these two taxa seem to have separated when the Benguela Current, as it exists today, was formed about 3-12 million years ago.

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinoptery ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Mugilidae
The mullets or grey mullets are a family (Mugilidae) of ray-finned fish found worldwide in coastal temperate and tropical waters, and some species in fresh water. Mullets have served as an important source of food in Mediterranean Europe since Roman times. The family includes about 78 species in 20 genera. Mullets are distinguished by the presence of two separate dorsal fins, small triangular mouths, and the absence of a lateral line organ. They feed on detritus, and most species have unusually muscular stomachs and a complex pharynx to help in digestion. Classification and naming Taxonomically, the family is currently treated as the sole member of the order Mugiliformes, but as Nelson says, "there has been much disagreement concerning the relationships" of this family. The presence of fin spines clearly indicates membership in the superorder Acanthopterygii, and in the 1960s, they were classed as primitive perciforms, while others have grouped them in Atheriniformes. They a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mossel Bay
Mossel Bay ( af, Mosselbaai) is a harbour town of about 99,000 people on the Southern Cape (or Garden Route) of South Africa. It is an important tourism and farming region of the Western Cape Province. Mossel Bay lies 400 kilometres east of the country's seat of parliament, Cape Town (which is also the capital city of the Western Cape), and 400 km west of Port Elizabeth, the largest city in the Eastern Cape. The older parts of the town occupy the north-facing side of the Cape St Blaize Peninsula, whilst the newer suburbs straddle the Peninsula and have spread eastwards along the sandy shore of the Bay. The town's economy relied heavily on farming, fishing and its commercial harbour (the smallest in the Transnet Port Authority's stable of South African commercial harbours), until the 1969 discovery of natural offshore gas fields led to the development of the gas-to-liquids refinery operated by PetroSA. Tourism is another driver of Mossel Bay's economy. Etymology The origi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kosi Bay
Kosi Bay is a series of four interlinked lakes in the Maputaland area of KwaZulu-Natal, South Africa. Ecology The lakes form part of the iSimangaliso Wetland Park, a UNESCO World Heritage Site. The closest town is Manguzi, some away from it. Kosi Bay estuary is only from the Mozambique border. It is possible to walk from the estuary to Ponta do Ouro in only an hour or so. It is one of the quietest beaches in South Africa. The Kosi River Mouth is known as "the aquarium" because of the clarity of the water and the abundance of fish species. Bird species in the area include the palm-nut vulture, Pel's fishing owl, white-backed night-heron, and kingfishers. Duiker, hippopotamus, crocodiles and bull sharks are also present, and loggerhead and endangered leatherback sea turtles lay their eggs on the beach. The Bay is noted for its aggressive bull shark population. The sharks are locally known as zambesi. Whale sharks and manta rays also visit the area. Whale watching to target ma ...

Diassanga Mullet
The Diassanga mullet (''Chelon bandialensis'') is a species of ray-finned fish, grey mullet from the family Mugilidae. It is found in the eastern Atlantic around the coasts of West Africa. Description The Diassanga mullet has a rounded, rather robust body with a pointed head which is about a quarter of the length of the body. The eye is surrounded by a small rim of adipose tissue and its upper lip has a thickness equal to a third of the diameter of the eye while the lower lip is much thinner. It has a silvery blueish-grey back with paler flanks which are marked with seven longitudinal grey lines. The anal and dorsal fins are yellow, as is the caudal fin but this has a black margin. They grow to in standard length. Distribution The Diassanga mullet is an eastern Atlantic species which occurs in the coastal waters of Senegal, Gambia and Guinea-Bissau. Habitat and ecology The Diassanga mullet is a relatively large and uncommon species within its distribution where it occurs i ...

Chelon
''Chelon'' is a genus of mullets found in coastal marine waters, estuaries and rivers in the Atlantic Ocean and Arabian Sea. Anatomy ''Chelon'' possesses the elongated body and dorsal fins typical of the order Mugiliformes, with frontal fins defined by four spines and anal fins with soft rays. The maximum sizes described vary between 15 cm for the Cape Verde mullet and 32 cm for the thicklip grey mullet. Habitat They are catadromous fishes, meaning that they can be found in lagoons and rivers as well as the sea during the reproductive season, fundamentally feeding on algae and diatoms. Taxonomy Recent cladistic analysis recovered ''Chelon'' as paraphyletic with respect to ''Liza'', so some species of ''Liza'' were reassigned to ''Chelon'' and ''Liza'' synonymized with ''Chelon''.Durand, J.-D., W.-J.
