Fig. 2

Schematic representation of the mantle margin in veliger larvae of Nodipecten nodosus. a Schematic representation of a cross-section through the larval body, anterior region to the top. b The unfolded mantle margin, framed in a, is divided into two regions, the distal and proximal ones, by the periostracum-forming zone. Abbreviations: drm, distal region of the mantle margin; fm, free mantle margin; ma, mantle; mm, mantle margin; sh, shell; pe, periostracum; pfz, periostracum-forming zone; prm, proximal region of the mantle margin; ve, larval velum
