Figure 1. Three-dimensional reconstruction of general anatomy, central nervous (CNS), circulatory, excretory, and anterior digestive systems of Strubellia paradoxa, paratype. (A) External morphology (contracted specimen, right view), arrowhead indicates position of diaphragm between head–foot and visceral sac; (B) overview of microanatomy showing internal organ systems; (C) CNS (posterior view, buccal ganglia omitted); (D) CNS, including buccal ganglia at left (right view); (E) excretory and circulatory systems (ventrolateral right view), asterisk indicates intersection between kidney and nephroduct; (F) buccal apparatus and anterior pedal gland, right view, asterisks indicate ciliated part of oesophagus. Abbreviations: ao, aorta; au, auricle; bc, bursa copulatrix; bg, buccal ganglion; bm, buccal mass; ccm, cerebral commissure; cg, cerebral ganglion; cns, central nervous system; dg, digestive gland; dkd, distal lumen of kidney; es, oesophagus; ey, eye; ft, foot; go, gonad; gog, gastro-oesophageal ganglion; gp, genital pore; ht, heart; kd, kidney; ln, labial tentacle nerve; nd, nephroduct; ndl, distal loop of nephroduct; np, position of nephroporus; oc, odontophore cavity; on, optic nerve; opt, optical
