Summary

Description

The Portuguese dogfish Centroscymnus coelolepis can reach 1.2 m in length. It is uniformly dark chocolate brown to golden brown in color. Like similar species it has no anal fin and the pelvic fins are positioned far back under the second dorsal. It can be identified by its short, stocky appearance and its very short snout. Its body, unlike similar species, does not taper abruptly from the pectoral region. It also has very small spines on both its dorsal fins. The tail is short but broad and the rear edge of its upper lobe is notched.

Recorded distribution in Britain and Ireland

Found off the western coasts of Ireland and Scotland as far north as the Shetland Isles.
