Being sessile creatures can come with its advantages and it can danger the animal substantially. Less energy is spent on movement, and resources are spent on growth and reproduction. Sessile tide pool organisms take advantage of the movement of the …

Movement. Although adult sponges are fundamentally sessile animals, some marine and freshwater species can move across the sea bed at speeds of 1–4 mm (0.039–0.157 in) per day, as a result of amoeba-like movements of pinacocytes and other cells. A few species can contract their whole bodies, and many can close their oscula and ostia ...Kingdom: Animalia

The Demospongiae are the largest class in the phylum Porifera. Their skeletons are made of spike-like structures consisting of fibers of the protein spongin and the mineral silica. Where the spike-like structures of silica are present, they have a different shape from those in the similar glass sponges.

Support Sponges include a system of pores (also called ostia) and canals, in which water passes. Water movement is driven by the beating of flagellae, which are located on specialized cells called choanocytes (collar cells). Sponges are either radially symmetrical or asymmetrical.

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. Under experimental conditions, researchers have shown that sponge cells spread on a physical support demonstrate a leading edge for directed movement.
