HabitatCentrophorus granulosus is a bathydemersal fully marine species which can be found offshore with a depth range of 50-1200 m.
- Moderatly sized shark reaching up to 160 cm in length.
- Drab uniform colouring from grey to olive green.
- First dorsal fin low but not particularly elongate.
- Large reflective green eyes.
- Small bladelike teeth larger in the lower-jaw than the upper-jaw.
- Posterior tips of the pectoral fins are noticeably long and angular.
Despite the relative abundance of Centrophorus granulosus and frequent commercial exploitation around the world, many aspects of its biology remain relatively unknown. It is known to feed on hake, lantern fish and other deepwater bony fish as well as squid (Compagno, 1984).
Unlike the leafscraper shark Centrophorus squamosus, the tooth-like projections on the of the gulper shark are flat and diamond-shaped without an elevated stalk. Furthermore the free rear tips of the pectoral fins are pointed and reach past the first dorsal fin spine.
