Faeces were collected from five specimens of Doris cf. ocelligera collected from Newlyn Marina, Newlyn, Cornwall. 11.05.16. Faeces were collected to determine the food source, which was a Halichondria species of sponge. A 0.1mm division rule was used for measurement and as a background for the images.

Specimen above found under a rock in a middleshore rockpool at Lariggan Rocks, Wherrytown, Penzance, Cornwall. 06.04.12. SW46795 29305.

This sea slug has up till now only been recorded from North and South Devon, Lyme Bay and Cornwall. It has been recorded from a wreck off Falmouth, but has been recorded three times at Penzance, on a wreck 1km off Chimney Rocks; found intertidally at Chimney Rocks, Lariggan Rocks and Long Rock, Penzance; with many specimens at Newlyn Marina, Newlyn, Cornwall, in 2015.

Thanks go to David Kipling for the initial identification of this species.

According to J. Prkić and I.F.Smith on The Conchological Society of Britain and Ireland's Encyclopedia of Molluscs, the images shown here have some differences from Mediterranean specimens of Doris ocelligera. Both forms have unipinnate gills, guard-tubercles around the gills and rhinophores and, frequently, fine dark apical spots on the tubercles. But these specimens have rhinophores the same colour as the mantle, and tubercles with constricted bases, while Mediterranean specimens have rhinophores distinctly different in colour from the mantle, and broad based tubercles. They may just be a regional variant, but might be a different species.

Please note, a white form can also be found.

Live specimens, photographs and records are needed to further research into this species. If you e-mail me I can put you in touch with the people conducting the research.

APHOTOMARINE supports open source data recording and sharing for the benefit of wildlife, recorders, research, science and education. The project recommends the following websites and works with the following bodies and organisations.

Marine Biological Association MBA

The Marine Biological Association or MBA, based in Plymouth, is one of the world’s longest-running societies dedicated to promoting research into our oceans and the life they support. Since 1884 the MBA has been providing a unified, clear, independent voice on behalf of the marine biological community.It has a growing membership in over 40 countries.

NBN National Biodiversity Network

The National Biodiversity Network or NBN is a charity that supports open source data sharing and recording supporting conservation, science and education. "Why do recorders need open source?". Simply because it supports the core values of wildlife recording and the free use of records and data over a very wide network that includes partners like the Natural History Museum.

The taxonomy used here is based on that of the following database, which is also used by the MBA, NHM and the NBN.

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.
