Specimens found on Codium in a large middleshore pool at Battery Rocks, Penzance, Cornwall. 30.04.16.

This is a tentative identification, but on speaking to others it seems quite logical that this is the species concerned. The species appears as Ectocarpus simplex in Lily Newton's 1931 book, "A Handbook of the British Seaweeds", which is where I first found reference to it before looking for the species on Codium.

The main objective of this website is in furthering environmental awareness and education through the medium of photography. To increase awareness and access to the wildlife of the region and help
people find and identify it. Sometimes the difference between species is obvious but many species can only be determined by observing microscopic characteristics that are specific to any one species.
