Basal region of field-collected aspidochirotid auricularia podocytes (po) showing pedicels that provide gaps or fenestrations (arrows) in an otherwise continuous epithelium. Pedicels that are not joined by filtration slit membranes are bridged only by the basal lamina (bl) supporting this mesothelium. Between pedicels the lumen (lu) of the axocoel and the blastocoel (be) are separated only by these extracellular connective tissue layers. Figure 18. Scale bar = i^m. Figure 19.
