Aplidium elegans, the sea-strawberry, is a species of colonial sea squirt, a benthic tunicate in the family Polyclinidae and class Ascidiacea.

[2] Aplidium elegans form firm, flattened globular masses, that look like pink cushions from 3 to 4 cm long.

[2] Colonial ascidians, like other benthic invertebrates show great morphological variability in terms of shape, size and color in response to both genetic characteristics and local environmental conditions.

[4] Aplidium elegans is found in the Atlantic Ocean, Mediterranean Sea, and the English Channel.

[4] The colony has a test or tunica which is a thick layer secreted by the mantle, containing cellulose and protecting the animal.
