Fig. 18. Model of WECB mechanics through maturation. Blue arrows denote sequential
movement from generalized structure to modified structure as described: (A)
generalized structure, (B) pre-ventral pedal gland (VPG; organ located in the
foot where a final stabilization process renders WECB insoluble), (C) during
VPG, and (D) post-VPG For detailed description, see text.
