This assessment is based on the information published in the 2005 shark status survey (Fowler et al. 2005).
The Borneo Shark (Carcharhinus borneensis) is known from very few records (most from Borneo), none of which are more recent than 1937. It was not recorded in the extensive George Vanderbilt Foundation shark collections in Thailand and Hong Kong (housed at the California Academy of Sciences, San Francisco, USA), the 1996/97 IUCN/SSC Shark Specialist Group and Sabah Fisheries Department survey of marine sharks in markets in Sabah, Borneo (Malaysia), or the 2000/01 WWF shark biodiversity study in the Philippines. Past records of this species are all from areas that have been and are being heavily exploited by artisanal and commercial fisheries and it is likely that these activities have detrimentally affected the Borneo Shark population.
|Range Description:||The Borneo Shark is an Indo-West Pacific species, recorded from Borneo (Kalimantan, Indonesia and Sarawak, Malaysia) and possibly also China (Chusan Island). Nominal and possible records also exist from Java (Indonesia) and the Philippines but these cannot yet be confirmed (Garrick 1982, Compagno 1984, 1988, in prep. b).|
Native:Indonesia (Kalimantan); Malaysia (Sarawak)
|FAO Marine Fishing Areas:||
Pacific – northwest; Pacific – western central
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||This is a rare shark that has not been recorded since 1937. Only five confirmed specimens are known.|
|Habitat and Ecology:||This is a small, rare inshore coastal shark, known only from five undoubted specimens (four of which were collected from Borneo) and very few valid localities. Virtually all details of its biology and life history parameters are unknown. The maximum size is estimated to be around 70 cm.|
|Major Threat(s):||This rare shark is (or was) found in areas that have been and are being heavily exploited by artisanal and commercial fisheries. These are likely to have detrimentally affected the population of this species, which has not been recorded since 1937.|
|Conservation Actions:||No conservation measures are in place for this species.|
