This Okenia has a broad flattened body and about nine elongate lateral papillae on each side of the mantle. These papillae are irregularly arranged and crowded and there are additional papillae arising from the back. The colour is bright pink with the papillae tipped with white or almost entirely white.[3] It is similar in shape, colour and diet to Okenia rosacea from the Pacific coast of America.
