| Pliotrema warreni Regan, 1906 |
The sixgill sawshark, Pliotrema warreni, the only member of the genus Pliotrema, is a sawshark of the family Pristiophoridae, found in the subtropical waters of the western Indian Ocean between latitudes 23° S and 37° S, at depths of between 60 and 430 m. Its length is up to about 1.7 m.
The sixgill sawshark is the only shark with a saw-snout and 6 pairs of gill slits. It is found on the continental shelf and upper slopes, feeding on bony fish, shrimp, mysids and squid. Reproduction is ovoviviparous, with 5 to 7 young in a litter. It probably uses its saw to stun and kill prey, and is sometimes caught by sports anglers.
Coloration is pale brown above and white below.
