Felimida purpurea, commonly known as the Purple Doris, is a stunning species of dorid nudibranch. This vibrant marine gastropod mollusc belongs to the genus Felimida, family Chromodorididae, superfamily Doridoidea, order Nudibranchia, class Gastropoda, phylum Mollusca, and kingdom Animalia. This species is prevalent in the Mediterranean Sea and along the Atlantic coasts of Europe and Africa, stretching from the Bay of Biscay to Cape Verde and as far west as the Azores.
Identifying Felimida purpurea is straightforward due to its distinctive and striking appearance. This chromodorid nudibranch features a plain white to pale purple mantle bordered with a line of orange-yellow. Within this yellow margin are noticeable white mantle glands embedded in the tissue. The rhinophores and gills are purple-pink with white tips. The body length of Felimida purpurea varies between 35 mm and 50 mm.
Felimida purpurea is characterized by its unique coloration and structure. The mantle is predominantly white or pale purple with an orange-yellow edge, and it contains irregularly shaped whitish glands visible through the transparent tissue. The rhinophores are crimson or purple with about 20 tightly set lamellae and a white apex. The gills, consisting of up to 17 branches in large specimens, are also purple with white tips. The foot extends well beyond the mantle border, with a yellow line running along its edge from the central area to the tail.
Felimida purpurea typically inhabits rocky infralittoral zones, often found under stones or on coralline sponges. It feeds on various sponge species, including Phorbas tenacior and Spongionella pulchella. This nudibranch is commonly encountered in its habitat, making it a frequent sight for divers exploring rocky underwater landscapes.
An interesting fact about Felimida purpurea is its taxonomic revision. Originally classified under the genus Chromodoris, this species was transferred to the genus Felimida following molecular analysis. This analysis revealed distinct genetic differences among Atlantic species of Chromodorididae, leading to a revised classification that better reflects the evolutionary history of these nudibranchs.
