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.
