Typically, calcareous sponges are small, measuring less than 10 cm (3.9 in) in height, and drab in colour. In an attempt to understand gastrulation in calcareous sponges and determine whether there might be homology of the germ layers between the Calcarea and other metazoans, we have studied the development, metamorphosis, structure and function of the calcareous sponge Sycon, a member of the Calcaronea, the sponges studied by Haeckel and by his followers. The sponges are many-celled animals, with three-cell layers, without a true digestive cavity, supported usually by calcareous or siliceous spicules, the body mass permeated by ciliated passages or containing minute chambers lined by flagellate, collared, monadlike cells.
