Description

The sixgill sawshark is a sawshark (Pristiophoridae) from coastal waters of the western Indian Ocean, off southern Africa. The species grows to about 1.7 metres and has a slender, yellow-brown body, six pairs of gill slits (unusual) and a long, flat, blade-like snout set with sideways-projecting teeth and a pair of long barbels. With this 'saw' it probes sand and mud bottoms and dislodges prey from the sediment. The saw can cause cuts when handled; remain cautious.
