This egg deposit from the nudibranch Aeolidia papillosa was attached to the side of a boulder. The boulder was turned for the photograph. The egg deposit was photographed dry whereas in the previous image another Aeolidia papillosa egg deposit was photographed underwater. There were two adult Aeolidia papillosa in the vicinity of this egg deposit, which was located close to the Guernsey end of the Lihou Island causeway.

This image shows a deposit of eggs of the nudibranch Aeolidia papillosa. Two adult Aeolidia papillosa nudibranchs were seen in the proximity of two deposits of Aeolidia papillosa eggs on the upper shore near the Guernsey end of the Lihou Island causeway on 9 May 2009. Aeolidia papillosa is the largest nudibranch that regularly visits the Guernsey inter-tidal area. It feeds on anemones, particularly beadlet anemones and snakelock anemones, which are both common on the Guernsey shore. File No. 090509 3857 ©RLLord fishinfo@guernsey.net
These two adult Aeolidia papillosa nudibranchs were on the upper shore in a shallow pool near the Guernsey origin of the Lihou Island causeway on the afternoon of 9 May 2009. Near-by were two deposits of spawn. The spawn is photographed in the adjacent images. These nudibranchs feed on sea anemones - particularly beadlet and snakelocks anemones. There cerata on the dorsal surface retain the nematocysts or stinging cells of the anemones they consume. File No. 090509 3851 ©RLLord fishinfo@guernsey.net

This light caramel coloured compound ascidian colony which measures 22 mm across has had four 2 mm diameter holes bitten out of it by the gastropod or snail Lamellaria perspicua which then has deposited its eggs inside so that when the snail embryos hatch they have an immediate food supply. Lamellaria perspicua feeds exclusively on compound ascidians or sea squirts. These snails have a fragile internal shell. They appear on the base of boulders and cobbles as a large periwinkle-sized dome or cap of rough tissue. File No. BG 080208 2921 ©RLLord fishinfo@guernsey.net
A poster up to A3 in size (40 x 28 cm) showing fifteen Guernsey nudibranchs and the spawn of the common sea slug, Berthella plumula. All these species are carnivorous. Depending on species they eat sponges, bryozoans, hydroids or anemones. The image of Aeolidia papillosa shows it attacking and devouring a snakelocks anemone, Anemonia viridis. Aeolidiella alderi is also attacking an anemone. Janolus cristatus and Polycella faeroensis both seen in the marinas of St. Peter Port harbour feed on bryozoans.
