A long, slender squid up to 90 cm in length with the fins forming an elongate diamond-shape in dorsal view, comprising two-thirds total body length. The tentacle club has median suckers only slightly larger than those on edges. The colour varies but pink, red and brown predominate. The shell has been reduced to a thin, internal horny pen.

Recorded distribution in Britain and Ireland

All British and Irish coasts.

Global distribution

Eastern Atlantic (20 degrees N to 60 degrees N), the Azores and West African coast south to the Canary Islands (its southern boundary is unknown), the Mediterranean Sea and the Red Sea.


Found over sandy and muddy bottoms. Migrate to shallows for spawning.  During the day they aggregate near the bottom and at night they disperse in the water column

Depth range

10 - 400 m

Identifying features

  • Mantle long, moderately slender, cylindrical.
  • Fins rhomboid, their length three quarters that of the mantle, their posterior borders slightly concave.
  • Tentacle club with median suckers only slightly larger than those on edges.
  • Colour - variable but pink, red and brown predominate.
