Here are some photos of Hermaea bifida. This was a first for me and ID'd by Dr Bernard Picton.
It is very pale in colour and Bernard suggests it had been feeding on a green or brown algae, anyway it was exceptionally well camouflaged. Sea temperature approx 10 deg C.
Locality: Kenmore Point, Loch Fyne, Scotland. Depth: 10 metres. Sea loch on west coast of Scotland. Length: 20 mm (approx). 15 May 2005. boulder slope. Photographer: Jim Anderson

Thanks for these photos. It is opportune to have them at the same time as I have been posting photos of a species of Aplysiopsis [see message #13862] as it shows the greatest external difference between the two genera, which is the almost total transparency of species of Hermaea, and the heavy pigmentation found in species of Aplysiopsis.
I have included some close-ups to show the shape of the cerata and the branching of the digestive gland within the cerata.
