Locomotion of Sponges and Its Physical Mechanism - ResearchGate

WebJSTOR Home WebLocomotion Sponges are generally sessile as adults and spend their lives attached to a fixed substratum. They do not show movement over large distances like other free-swimming marine invertebrates. However, sponge cells are capable of creeping along substrata via organizational plasticity. Websponge surface except for the oscular rim (Fig. IB). The external coat is thin and uplifted by the underlying spicules (Fig. IB). Occasionally the characteristic tripods are discernible (Fig. 1C). The atrial cavity is lined by a single layer of choanocytes (Fig. ID) arranged side by side in a tight configuration. The continuity of choanoderm is toxic segs
