Argyrosomus coronus, also known as the westcoast dusky kob, [2] is a species of marine ray-finned fish belonging to the family Sciaenidae, the drums and croakers. It is found on the west coast of Southern Africa, from southern Angola to northern Namibia and part of South Africa.
Argyrosomus coronus was first formally described by M. H. Griffiths, M.H. and P. C. Heemstra in 1995. [3]
The species has a distribution confined to the Angola–Benguela Frontal Zone (ABFZ) of the southeastern Atlantic Ocean. A study revealed that during a period of local warming, the species extended its distribution into Namibian waters, where it hybridised with the resident and congeneric Argyrosomus inodorus . [4]
Adults migrate in correlation with the movement of the Angola–Benguela frontal zone, travelling northward as far as Gabon in winter and returning to southern Angola in spring, coinciding with what appears to be offshore spawning. [5]
Heaviside's dolphin is one of four dolphins in the genus Cephalorhynchus. The small cetacean is endemic to the Benguela ecosystem along the southwest coast of Africa.
The Atlantic humpback dolphin is a species of humpback dolphin that is found in coastal areas of West Africa.
The Benguela Current is the broad, northward flowing ocean current that forms the eastern portion of the South Atlantic Ocean gyre. The current extends from roughly Cape Point in the south, to the position of the Angola-Benguela front in the north, at around 16°S. The current is driven by the prevailing south easterly trade winds. Inshore of the Benguela Current proper, the south easterly winds drive coastal upwelling, forming the Benguela Upwelling System. The cold, nutrient rich waters that upwell from around 200–300 m (656–984 ft) depth in turn fuel high rates of phytoplankton growth, and sustain the productive Benguela ecosystem.
Thyrsites atun, known as the snoek in South Africa and as the barracouta in Australasia, is a long, thin species of snake mackerel found in the seas of the Southern Hemisphere, and a popular food fish in South Africa, particularly along the west and southwest coast. Despite its Australasian name, it is not closely related to the barracuda.
The sharptooth houndshark or spotted gully shark is a species of houndshark in the family Triakidae found in shallow inshore waters from southern Angola to South Africa. Favoring sandy areas near rocky reefs and gullies, it is an active-swimming species that usually stays close to the bottom. This robust shark reaches 1.7 m (5.6 ft) in length and has characteristically large, rounded fins; the pectoral fins in particular are broad and sickle-shaped in adults. It also has a short, blunt snout and long furrows around its mouth. This species is gray or bronze in color above, with variable amounts of black spotting.
Argyrosomus is a genus of marine ray-finned fishes belonging to the family Sciaenidae, the drums. The fish in this genus are large and are commonly targeted as game fish.
The African chimaera is a species of fish in the family Chimaeridae found near Kenya, Mozambique, Namibia, and South Africa. Its natural habitat is deep-waters up to the depth of 750 m Eight species of chimaera are found in the southern African region, representing the three families and all six genera.
Cynoglossus capensis, commonly known as the sand tonguesole, is a species of tonguefish.
Merluccius capensis is a ray-finned fish in the genus Merluccius, found in the south-eastern Atlantic Ocean, along the coast of South Africa. It is a long, lean fish with a large head, similar in appearance to the European hake and the deep-water Cape hake. By day, it lives close to the bottom on the continental shelf and upper slope at depths not usually exceeding 400 m (1,300 ft); it makes a large, daily vertical migration rising at night to feed in the nectonic zone, and it also migrates southwards in spring and northwards in autumn. It is an important commercial fish species in southern Africa.
Boops is a genus of marine ray-finned fishes belonging to the family Sparidae, the seabreams and porgies. There are two species in this genus, one in the Western Atlantic and Mediterranean, and the other in the Western Indian Ocean.
Chrysoblephus gibbiceps, the red stumpnose, red stumpnose seabream or Miss Lucy, is a species of marine ray-finned fish belonging to the family Sparidae, the seabreams and porgies. This fish is endemic to the southwestern Indian Ocean off the coast of South Africa. The International Union for Conservation of Nature classifies this species as Endangered.
Chrysoblephus laticeps, the red roman or roman seabream, is a species of marine ray-finned fish belonging to the family Sparidae, the seabreams and porgies. This fish is endemic to Southern Africa, ranging from Namibia to the Eastern Cape.
The west coast seabream or west coast steenbras is a species of marine fish in the family Sparidae. It is found in very shallow water off the coasts of to Angola, Namibia and South Africa. The International Union for Conservation of Nature lists its conservation status as being "near threatened".
Umbrina canariensis, the Canary drum is a warm water, marine fish of the family Sciaenidae which is found in the western Mediterranean, eastern Atlantic Ocean and western Indian Ocean. Other English vernacular names are tesselfish, baardman, checker drum, common baardman, tasselfish and bellman.
Umbrina ronchus, the fusca drum, slender baardman, roncador, fusca croaker or slender tasselfish, is a species of croaker or drum from the family Sciaenidae which is found in the western Atlantic Ocean and the Mediterranean Sea.
Vema Seamount is a seamount in the South Atlantic Ocean. Discovered in 1959 by a ship with the same name, it lies 1,600 kilometres (1,000 mi) from Tristan da Cunha and 1,000 kilometres (620 mi) northwest of Cape Town. The seamount has a flat top at a mean depth of 73 metres which was eroded into the seamount at a time when sea levels were lower; the shallowest point lies at 26 metres depth. The seamount was formed between 15-11 million years ago, possibly by a hotspot.
Argyrosomus inodorus, the mild meagre or silver kob, is a species of marine ray-finned fish belonging to the family Sciaenidae, the drums and croakers. The species is found off southern Africa where it is an important target species for hook and line fisheries.
The Angola - Benguela front (ABF) is a permanent frontal feature situated between 15° and 17°S off the coast of Angola and Namibia, west Africa. It separates the saline, warm and nutrient-poor sea water of the Angola Current from the cold and nutrient-rich sea water associated with the Benguela Current.
Semimytilus algosus is a species of mussels. A common name for this species is Dwarf mussel. It is the first species where trioecy was reported in the phylum Mollusca.
Argyrosomus hololepidotus, also known as the Madagascar meagre or southern meagre, is a species of marine ray-finned fish belonging to the family Sciaenidae, the drums and croakers. The species is endemic to Madagascar and the Indian Ocean.
