Dichichthys Melanobranchus

Specimens can attain a total length of at least , have elongated cat-like eyes, and have two small dorsal fins set far back. They’re oviparous and lay one egg at a time. This shark is a potential bycatch Bycatch (or by-catch), in the fishing industry, is a fish or other marine species that is caught unintentionally while fishing for specific species or sizes of wildlife.

In the upper jaw, there are rods of blunt, flat teeth with 3 cusps, likely used for crushing, as well as row of sharper teeth with the mid, central cusp longer and to a point. The bottom te ...

Dichichthys
''Dichichthys'' is a genus of sharks which is the only genus in the monotypic Family (biology), family Dichichthyidae, the bristle sharks. These sharks are found in the Western Pacific Ocean. Until recently, scientists believed these 5 species were part of the genus ''Parmaturus,'' until morphological testing confirmed its placement in its own family. Supraorbital crests on the chondrocranium also distinguish ''Dichichthys'' from other catshark genera/families. Species ''Dichichthys'' contains the following five recognised valid species: * ''Dichichthys albimarginatus'' (Bernard Séret, Séret & Peter R. Last, Last, 2007) (Whitetip bristle shark) * ''Beige catshark, Dichichthys bigus'' (Séret & Last, 2007) (Beige bristle shark) * ''Dichichthys melanobranchus'' (W. L. Chan, 1966) (Blackgill catshark) * ''Dichichthys nigripalatum'' (Fahmi Fhami, Fahmi & David A.

Continental Slope
A continental margin is the outer edge of continental crust abutting oceanic crust under coastal waters. It is one of the three major zones of the ocean floor, the other two being deep-ocean basins and mid-ocean ridges. The continental margin consists of three different features: the continental rise, the continental slope, and the continental shelf. Continental margins constitute about 28% of the oceanic area. Subzones The continental shelf is the relatively shallow water area found in proximity to continents; it is the portion of the continental margin that transitions from the shore out towards to ocean. Continental shelves are believed to make up 7% of the sea floor. The width of continental shelves worldwide varies in the range of 0.03–1500 km. The continental shelf is generally flat, and ends at the shelf break, where there is a drastic increase in slope angle: The mean angle of continental shelves worldwide is 0° 07′, and typically steeper closer to the coa ...

Bycatch
Bycatch (or by-catch), in the fishing industry, is a fish or other marine species that is caught unintentionally while fishing for specific species or sizes of wildlife. Bycatch is either the wrong species, the wrong sex, or is undersized or juveniles of the target species. The term "bycatch" is also sometimes used for untargeted catch in other forms of animal harvesting or collecting. Non- marine species ( freshwater fish not saltwater fish) that are caught (either intentionally or unintentionally) but regarded as generally "undesirable" are referred to as rough fish (mainly US) or coarse fish (mainly UK). In 1997, the Organisation for Economic Co-operation and Development (OECD) defined bycatch as "total fishing mortality, excluding that accounted directly by the retained catch of target species". Bycatch contributes to fishery decline and is a mechanism of overfishing for unintentional catch. The average annual bycatch rate of pinnipeds and cetaceans in the US from 1990 t ...
