Do Sponges Have Cephalization. sponges appear to represent an early stage of multicellularity in the animal clade. The evolution of invertebrates from the earliest sponge species. yes, those spines are part of an internal skeleton. They have a front, back, top and bottom. Although they have specialized cells for particular functions, they lack true tissues in which specialized cells are organized into functional groups. Sponges are similar to what might have been the ancestor of animals: the head of a cephalized organism contains a concentrated group of nerves, or brain, that controls the rest of the organism, as well as specialized organs for consumption and perception, like mouths, eyes and ears. However, unlike higher metazoans, the cells that make up a sponge are not organized into tissues. They pull water into the spongocoel (middle cavity of a sponge). cnidarians are radially symmetrical (i.e., similar parts are arranged symmetrically around a central axis). how sponges feed: unlike protozoans, the poriferans are multicellular. Cephalized organisms exhibit a distinct division between parts of the body;
