and diversity of marine life that can be found in coastal waters
and intertidal areas of Great Britain and Ireland by David Fenwick.

The specimen above isn't the best specimen of this species in the world as it doesn't have the three large rimmed rhinophores that is associated with typical individuals. The specimen here could very easily be confused with the common species Facelina auriculata. As there was an issue with the identification and the species unlikely be determined with any accuracy through photography, the animal was dissected as it was the only way without sequencing to determine what the species was.

The radula teeth and jaws were examined under a compound microscope and were found to be more typical of the genus Favorinus, as the radula teeth were found to be longer than Facelina. The 3mm specimen was found at Newlyn Marina, Newlyn, Cornwall, 04.10.18.

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.

Conchological Society of Great Britain and Ireland

The Conchological Society of Great Britain and Ireland
Helping to understand, identify, record, and conserve molluscs.

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.
