Abstract
Many soft bodied coelenterates are highly deformable or contractile. In the absence of hard skeletal elements, the epithelia are subjected to mechanical forces which cause a wide range of structural changes in the component epithelial cells. What kinds of structural change occur and how are the cells adapted to them? These questions are addressed with reference to cell surface area, cell membranes, cell junctions and epithelial cilia.
