Borneo shark
carcharhinus borneensis latin

Almost nothing is known about the natural history of the Borneo shark.

Bony fishes are probably the main food of the Borneo shark.

The evolutionary relationships of the Borneo shark are uncertain.

While an extant population has since been found, the Borneo shark continues to merit conservation concern given its highly limited range within heavily fished waters.

The Borneo shark's conservation status remains precarious given its very small range in waters subjected to intensive artisanal and commercial fishing.

Carcharhinus borneensis (Borneo shark)

The Borneo shark resembles the sharpnose sharks (Rhizoprionodon) in certain traits, for example the enlarged pores by its mouth.

The Borneo shark (Carcharhinus borneensis) is a species of requiem shark, family Carcharhinidae.

The Borneo shark is slim-bodied, with a long, pointed snout and oblique, slit-like nostrils preceded by narrow, nipple-shaped flaps of skin.

The International Union for Conservation of Nature last assessed the Borneo shark as Endangered, based on 2005 data that do not include the recent specimens from Mukah.

Dutch ichthyologist Pieter Bleeker originally described the Borneo shark as Carcharias (Prionodon) borneensis in an 1858 issue of the scientific journal Acta Societatis Regiae Scientiarum Indo-Neêrlandicae.

All recent specimens of the Borneo shark have been collected solely from fishery landing sites at Mukah in Sarawak, despite thorough surveys across the rest of Borneo (including at the locality of the type specimen).
