Ganges shark [SEP] IUCN conservation status
Ganges shark
The Ganges shark ("Glyphis gangeticus") is a critically endangered species of requiem shark found in the Ganges River (Padma River) and the Brahmaputra River of Bangladesh and India. It is often confused with the more common bull shark ("Carcharhinus leucas"), which also inhabits the Ganges River and is sometimes incorrectly referred to as the Ganges shark. Unlike bull sharks, which need to migrate to salt water to reproduce, species in the genus "Glyphis" are true river sharks. The genus
incidentally by coastal gillnet fisheries and perhaps also by line and trawl fisheries. The International Union for Conservation of Nature (IUCN) lacks sufficient data to assess the conservation status of this species except in Australian waters, where its population seems healthy and has been listed under Least Concern.
Taxonomy and phylogeny.
Australian ichthyologist Gilbert Percy Whitley originally described the nervous shark as a subspecies of "Galeolamna greyi" (a junior synonym of "Carcharhinus obscurus", the dusky shark), in a 1945 issue of the scientific journal
