Mahseer is the common name used for the genera Tor, Neolissochilus, and Naziritor in the family Cyprinidae (carps). The name is, however, more often restricted to members of the genus Tor. The range of these fish is from Malaysia, Indonesia, and across southern Asia including the Indian Peninsula and Pakistan. They are commercially important game fish, as well as highly esteemed food fish. Mahseer fetch high market price, and are potential candidate species for aquaculture. Several of the larger species have suffered severe declines, and are now considered threatened due to pollution, habitat loss, and overfishing.

It is generally most numerous at depths between 80 and 200 m (260–660 ft), but performs a seasonal migration to inshore regions when it can occur as shallow as 20 m (65 ft). It is predatory, feeding on fish and prawns, and grows to a total length of 30 cm (1 ft). This species was formerly regarded as the only formally described member of its genus., however, another species, Hemibates koningsi, which was formerly referred to as referred to as Hemibates sp.

Pristiophorus is a genus of sawsharks found in the Pacific, Atlantic and Indian oceans. Members of this genus differ from the Sixgill Sawshark (Pliotrema warreni) in having five gill slits.
