Spiral wrack

Fucus spiralis

Description:

Fucus spiralis is olive brown in colour and similar to Fucus vesiculosus and Fucus serratus. It grows to about 30 cms long and branches somewhat irregularly dichotomous and is attached, generally to rock, by a discoid holdfast. The flattened blade has a distinct mid-rib and is usually spirally twisted without a serrated edge, as are to be seen in Fucus serratus, and it does not show air-vesicles, as Fucus vesiculosus.

Habitat:

Rocks at the beach

Project Noah Fun Fact: The term seaweed is an informal term used to describe macroscopic, multicellular marine algae. These algae inhabit ocean waters that are close to the shore and receive plenty of sunlight. These plant-like organisms are not plants at all, but they do have the ability to photosynthesize. The modern study of marine and freshwater algae is called either phycology or algology. Seaweed is often used by humans as food, medicine, fertilizer, fuel and dyes.
