Sponges are sessile, feed by phagocytosis, and reproduce sexually
... Sponges are generally sessile as adults and spend their lives attached to a fixed substratum. They do not show movement over large distances as do freeswimming marine invertebrates. However, sponge cells are capable of creeping along substrata via organizational plasticity. Under experimental condi ...
