Summary

Description

The leafscraper shark Centrophorus squamosus is a moderately large deep water dogfish 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 eyes. The leafscraper 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.

Found off the western coasts of Scotland and south-west Ireland, although may be under-recorded.

  • Large reflective green eyes.
  • Small bladelike teeth larger in the lower-jaw than the upper-jaw.
  • Posterior tips of the pectoral fins are broadly angular but not strongly extended.
