Sea Slugs of Summer

Polycera quadrilineata

Beatiful Sea Slugs! all found by my son Henry this Summer.
Henry has found Grey Sea Slug and Sea Hare in the past but not recently.

This common European polycerid grows to about 40 mm in length. It is white with blotches of yellow or orange. Sometimes black spots or speckling can be present. The orange marks usually from a line down the dorsal midline, with others in the sides and dorsal part of the posterior foot. In some animals, as illustrated here, black or dark blue speckling occurs. The rhinophores, gills and tentacles are tipped with orange, and in some cases the gills are edged in orange. There usually four pointed papillae around the anterior (head end) of the mantle. It feeds on ectoproct bryozoans, especially Membranipora membranacea, but is also reported from a number of other species.

Thanks for the info Sea Slug Forum

2 mating Sea Slugs with very young voyeuristic purple Lumpsucker.

Also Polycera quadrilineata with the rare dark spotted markings.

Elysia viridia

Elysia viridis or The Sap-Sucking Slug is a small-to-medium-sized species of green sea slug, a marine opisthobranch gastropod mollusc in the family Placobranchidae.

This sea slug resembles a nudibranch, but it is not closely related to that order of gastropods.
It is instead a sacoglossan. thanks Wikipedia
