Transmission electron micrographs of sections through the somatocoels ol'aspidochirotid auriculariae. Figure 7. The epithelium lining the lumen (lu) of the somatocoel is composed of squamous and columnar monociliated cells. Scale bar = pm; be, blastocoel; ci, cilium; nu, nucleus; pc, paracellular space. Figure 8. Large paracellular spaces (pc) lead to channels suggestive of transfer tubules (arrowhead). Scale bar = MTU lu, lumen of somatocoel; mi, mitochondrion; nu, nucleu
