Images of species taken at Sennen Cove, Penwith, Cornwall. 15.12.11. SW 35630 26665.

The species, with its eggs, was found amongst a colony of Lepas anatifera (Stalked or Goose barnacles) on a short piece of sleeper type timber. The timber also contained the shipworms Bankia gouldi, Teredora malleolus and Nototeredo norvagica; and also two, one male and one female Planes minutus, known as Columbus crabs. The timber had obviously drifted across the Atlantic from the Western Atlantic or Caribbean Sea.

Fiona pinnata feeds on both Lepas species, which gives the slug its brown colour here in the images; but also on Velella velella, By the wind sailor, which turns the animal a bluish colour.

The common name Noble aeolis is taken from a Victorian text, Shell Life by Edward Step.

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.

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.
