Euselenops luniceps has many modifications for living in a sandy environment which are described on a separate page. It is easily recognised by its flattened, broad rounded shape, and large oral veil, fringed with sensory papillae. In most pleurobranchs the foot and mantle are of similar size but in Euselenops the foot is much larger. Posteriorly, the mantle folds into a relatively long siphon or tube, which allows the mantle cavity and gills to remain in contact with fresh seawater while the animal is buried in the sand.

See page describing and illustrating adaptations for living in sand.
