3D tomographic reconstruction of Chrysomallon squamiferum, the full anatomical model in various views. Soft body outline (mantle and foot) shown in transparency. Ctenidium, anterior oesophagus, oesophageal gland, and digestive gland are rendered semi-transparent to show structures underneath. For all parts, the tomographic model is shown to left and a second copy of the same view with labelled parts shown to right. a. Dorsal view. b. Ventral view. c. Frontal view. Each colour group corresponds to a specific anatomical system: grey/black, digestive tract; green, oesophageal gland; translucent blue, ctenidium; red, circulatory system (excluding ctenidium); fuchsia, nervous system. Abbreviations: a, auricle; ac, anterior commissure; ct, ctenidium; dg, digestive gland; i, intestine; ln, lateral (visceral) nerve; ls, lateral swelling; mn, mantle nerve; ne, nephridium; oe, oesophagus; og, oesophageal gland; on, osphradial nerve; pn, pedal nerve; ps, pleural swelling; r, radula; rc, radula cartilage; re, rectum; sd, duct connecting stomach to digestive gland; sg, blood sinus under the ctenidium; si, blood sinus; ss, statocyst; st, stomach; tn, tentacular nerves; v, ventricle; ve, blood vessel. Scale bars: 250 μm
