Fucus ceranoides

Fucus ceranoides is a species of brown algae found in the littoral zone of the sea shore.[1]

Description

Fucus ceranoides is a species similar to other species of Fucus. It is linear to about 1 cm wide and is attached by a discoid holdfast. The branches grow to a length of 60 cm and show a clear midrib. Its margin is entire and it differs from Fucus serratus in not having a serrated edge and unlike Fucus vesiculosus it does not have air vesicles, however irregular swellings gives it a resemblance to F. vesiculosus. Fucus spiralis has spirally twisted fronds.[2][3]

Distribution

Fucoids have no planktonic dispersal stages, restricting gamete dispersal.[4] They can be found on the shores of Ireland and Great Britain including the Isle of Man and Shetland.[3]

Habitat

Fucus ceranoides is restricted to estuarine intertidal habitats under fluctuating salinities. The modern distribution of Fucus ceranoides ranges from Portugal to Norway and Iceland. [5][6][7] This includes the rocky shores in the littoral generally where fresh water flows into the sea, brackish water in sheltered bays.[2][3][8]
