Hydrolagus Erithacus
''Hydrolagus erithacus'', or Robin's ghostshark, is a species of fish in the family Chimaeridae. It is found in the southeastern Atlantic and southwestern Indian oceans. There exists a rapid development of fisheries since the 1970s in their territory, targeting deepwater sharks. While there is no data available for ghost sharks in this region, the South African Prince Edward Islands Marine Protected Areas may provide refuge to this species. References erithacus ''Erithacus'' (Greek: "robin" (erithacos)) is a genus of passerine bird that contains a single extant species, the European robin ''(Erithacus rubecula)''. The Japanese robin and Ryukyu robin were also placed in this genus (as ''Erithacus akahige ... Fish of the Atlantic Ocean Fish of the Indian Ocean Fish described in 2017 {{Chondrichthyes-stub ...

Fish
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. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

Chimaeridae
The Chimaeridae, or short-nosed chimaeras, are a family of cartilaginous fish. They resemble other chimaeras in general form and habits, but have short, rounded snouts, without the modifications found in related families. Many species have long, tapering tails, giving them an alternative name of ratfish. Shortnose chimaeras have a venomous spine on their backs, which is sufficiently dangerous to injure humans. They are found in temperate and tropical marine waters worldwide. Most species are restricted to depths below , but a few, notably the spotted ratfish and rabbit fish, can locally be found at relatively shallow depths. They range from in maximum total length, depending on species. Species The species are grouped into two genera and include: Family Chimaeridae * Genus ''Chimaera'' Linnaeus, 1758 ** '' Chimaera argiloba'' Last, W. T. White & Pogonoski, 2008 (whitefin chimaera) ** '' Chimaera bahamaensis'' Kemper, Ebert, Didier & Compagno, 2010 (Bahamas ghostshark ...

Prince Edward Islands Marine Protected Area
The Prince Edward Island Marine Protected Area is an offshore conservation region near the Prince Edward Islands in the exclusive economic zone of South Africa, nearly 2,000 km southeast of South Africa in the Indian Ocean. The MPA provides habitat for seals, killer whales, breeding seabirds and Patagonian toothfish. History The Prince Edward Islands have been managed as a special nature reserve since November 1995, but there was originally no marine component. The Minister of Environmental Affairs and Tourism (DEAT), Martinus van Schalkwyk, announced South Africa's intention to declare a large MPA around the sub-Antarctic Prince Edward Islands in June 2004. This was followed by consultation between DEAT and WWF to guide the implementation of this MPA. The result was a compromise between conservation and commercial fishing interests based on the available information. The Minister of Water and Environmental Affairs Bomo Edith Edna Molewa, declared a Marine Protected ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
