Abstract:
A glandular cushion, called the pedal aperture gland in this paper, lies adjacent and internal to each of the two mantle margins composing the pedal aperture of the soft-shelled clam Mya arenaria. Two types of glandular cells are found in the glands. The principal type (bacillary mucous cell) manufactures secretory vesicles that contain discrete protein-rich fibers in a matrix of glycoprotein. The second type (mucous goblet cell) produces sulfated and nonsulfated mucosubstances. The glands function in the formation of pseudofeces from particulate material, especially burrow sediments that enter the mantle cavity through the pedal aperture. Their possible phylogenetic relationship to similar glands in other bivalves is discussed briefly.
