Summary

Description

The gulper shark Centrophorus granulosus is a moderately large deep water member of the dogfish family reaching up to 160 cm in length. It has a uniform drab-gray dorsal colouring and a slightly paler ventral colouring. It has a moderately long and broad snout and large reflective green eyes. The gulper shark does not have an anal fin and has two dorsal fins. The first dorsal fin is quite short and the second is relatively high when compared to similar species. Both have prominent spines. Lateral tooth-like projections are present on the body.

Identifying features

  • 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.

Additional information

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.
