Summary

Description

Laminaria ochroleuca is a yellow-brown digitate kelp up to about 1.5 m in length. It has a distinct yellow area at the junction of the stipe and the blade which is a key distinguishing feature. Laminaria ochroleuca also has a rigid round stem (or stipe) that is clean of any attached growths (epiphytes). The blade is broad and flattened, dividing into numerous strap like digits.

Recorded distribution in Britain and Ireland

An isolated recording in the Shetland Islands but otherwise found on the coast of south west England including Lundy, the Isles of Scilly, south Devon and Cornwall.

Global distribution

NE Atlantic, Mediterranean, SE Atlantic

Habitat

The species is found on rocks from the low water spring tide level to the shallow subtidal. In some locations Laminaria ochroleuca may be found in deeper water. For example, in the Isles of Scilly a park of Laminaria ochroleuca is found deeper than Laminaria hyperborea at a depth of about 25 m. The species may occur as mono-specific stands or as mixed stands with other Laminaria species.

Depth range

Identifying features

  • Bright yellow patch at base of blade.
  • Similar in appearance to Laminaria hyperborea but with a rigid round epiphyte free stipe.
