Abstract Histological and ultrastructural studies of free-swimming and attached larvae of Diplosoma listerianum Milne Edwards indicate that initial attachment is by means of papillae, which secrete an adhesive substance. The source of the adhesive is the central mass cells of the papilla. These cells secrete large electron-dense granules, and also a mass of reticular material. The granules give rise to the adhesive seen in sections and scanning electron micrographs of attached larvae, although the reticular material may also contribute to the adhesive. Histochemical tests show that protein is present in the granules, together with a small amount of carbohydrate. The reticular material contains sulphated acid mucopolysaccharide.
