Specimens above found in a sample of Coral Weed, Corallina officinalis, collected from a large middleshore pool at Battery Rocks, Penzance, Cornwall. 17.06.16.
Okenia aspersa is not a common species in Cornwall, nor is it usually found in intertidal pools, so it's rather an odd find. The nearest record of the species is at St. Ives, a record by Vallentin, who found a specimen between 1903 and 1906.
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.
