Description:
Fucus spiralis is an intertidal brown seaweed that grows up to 40 cm long, without air bladders and that lives for up to 4 years. This species can tolerate a high level of desiccation. 
It typically forms a zone high on rocky shores, below Pelvetia but above the other large brown seaweeds (e.g. Ascophyllum nodosum, Fucus vesiculosus) that characterise the mid-shore. It has the common names of spiral wrack and flat wrack.
Well grown plants are usually easily recognisable by the flattened, dichotomously branched thallus, lacking bladders, twisted and the large, oval receptacles at the frond tips, each receptacle being surrounded by a narrow rim of vegetative frond. Nevertheless, younger plants are not always so easy to identify, and even mature plants can be confused with F. ceranoides or with bladderless forms of F. vesiculosus. Both of these species, however, have narrower, more pointed, rimless receptacles.
