Plocamopherus maderae is a species of sea slug, a nudibranch, a shell-less marine gastropod mollusk in the family Polyceridae.[1]

Description

[edit]

This nudibranch is orange or yellow-orange in colour, with numerous small dark brown spots and fewer, larger, poorly-defined, orange spots and patches. The mantle edge has three pairs of branched papillae, one behind the branchial plume, one in front and one mid-way along the back. These are marked with white pigment and there is a variable amount of white pigment along the mantle edge and behind the gills. The papillae behind the branchial plume bear rounded bioluminescent organs. The tail is long, flattened and has a dorsal crest. It is muscular and can be used for swimming. The gills are large, sparsely branched and held erect. The rhinophores have lamellate tips and a tapering stalk and are similar in colour to the body. Maximum size is about 50 mm.[2] This nudibranch is normally nocturnal, hiding beneath boulders in shallow water during daytime.

Distribution

[edit]

This species was described from Madeira. It has subsequently been reported from the Canary Islands and the Cape Verde Islands.[1][3][4]
