Sixgill Sawsharks [Pliotrema]

Description

Pliotrema is a genus within the Pristiophoridae family, distinct for having six pairs of gill slits, unlike most other sharks which typically have five. This genus is known for its unique snout, equipped with sharp teeth on either side, used for hunting and self-defense. Sixgill Sawsharks are relatively rare and are found in the Indian Ocean and off the southern coasts of Africa. They inhabit deep waters and are known to feed on a variety of marine organisms, including fish, crustaceans, and squid. Their elongated snouts and the presence of six gill slits make them easily distinguishable from other members of their family.
