Two nudibranchs meet and mouth each other - Facelina auriculata on the left and Facelina bostoniensis on the right. They are gliding over erect bryozoan colonies and a Mogula ascidian on the lower edge and in the middle of the image. They were feeding and laying egg veils on the side of the pontoon attached to the fish quay in St. Peter Port harbour, Guernsey on the 8th June 2007.

This image shows a close-up of the head of Facelina bostoniensis. The rhinophores are furnished with rings (annulate). The oral tentacles are very long and partially curled in this image. The brown digestive gland shows through the transparent cerata that cover the dorsal surface of the nudibranch. This species was feeding and laying egg veils on the side of a pontoon attached to the fish quay in St. Peter Port harbour, Guernsey on the 8th June 2007.

The nudibranch, Facelina auriculata, gliding over the invertebrate fauna growing on a pontoon attached to the fish quay in St. Peter Port harbour, Guernsey. Behind Facelina auriculata is the sea slug Facelina bostoniensis. Photographed on the 8 June 2007. File No. 080607 7-917 ©RLLord fishinfo@guernsey.net
On the 8 June 2007 I found three species of nudibranch including this species, Facelina annulicornis, gliding over the turf on the side of the pontoons attached to the fish quay in St. Peter Port harbour, Guernsey, Channel Islands. There were several different egg veils or egg deposits on various substrates but I couldn't tell which sea slug the various egg deposits belonged to. There is a Jassa amphipod to the left of the sea slug and a small caprellid amphipod just above the mouth of the slug. File No. 080607 21-917 ©RLLord fishinfo@guernsey.net
This beautiful nudibranch, Facelina annulicornis, was seen on the side of the pontoons attached to the fish quay in St. Peter Port harbour, Guernsey on the 8th June 2007 along with two other sea slug species. The other species can be seen in the distance - Facelina bostoniensis and Facelina auriculata. Dr. Bernard Picton in his excellent book "A Field Guide to the Nudibranchs of the British Isles" writes that Facelina annulicornis has been known to attack and consume some other sea slug species.

This nudibranch, Facelina annulicornis, was one of three species of sea slug I found feeding and depositing eggs on the side of a pontoon attached to the fish quay in St. Peter Port harbour, Guernsey on the 8 June 2007. File No. 080607 19-917 ©RLLord fishinfo@guernsey.net
These sea anemones, Actinothoe sphyrodeta, grow on the side of the pontoon on the inside of the arm of the fish quay. Some people have given them the common name "fried egg anemone". They can resemble the anemone Sagartia elegans but they don't possess suckers on the column. The column has pale stripes. This can be seen on the anemone in the extreme lower left of the image. These anemones were photographed on the 8 June 2007. File No. 080607 384 ©RLLord fishinfo@guernsey.net
I examined the north side of a string of pontoons inside the arm of the fish quay in St. Peter Port harbour, Guernsey and found three species of nudibranch or sea slug feeding and laying their spawn on their food growing on the side of the pontoon. This is an image of Facelina annulicornis found on the side of the pontoon on the 8 June 2007. File No. 080607 506 ©RLLord fishinfo@guernsey.net
