Numerous specimens of the opisthobranch mollusc Runcina coronata were found with a turbellarian parasite, the Runcina being found in a small sample of coralline algae scraped from a pool on the lowershore at Bovisand Beach, near Plymouth, Devon, 19.04.22. This is the first time I have seen this parasite outside of Mounts Bay so is therefore a more common occurence, and likely a seasonal one.

- area and position of 300mm x 300mm scrape sample where the specimen was found 1

Specimen above was found in a 300mm x 300mm scrape sample of Corallina officinalis, Coral Weed, in an area of seepage below a pool on the lowershore at Skilly, near Newlyn, Cornwall, 29.05.18. Specimen sent to the Natural History Museum in London for molecular analysis. Over 100 species were recorded in the 300mm x 300mm sample.

Yakko Hirano reports the species here appears similar to one reported on an Aplysia, another species of opisthobranch mollusc, that was found by Kosuke Sudo in Japan.

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.
