WebbLike the square-panted tube sponge, 98 percent of the roughly 5,000 species of sponges live in the ocean. Sponges are essentially tissue sacs that let water flow through their bodies to filter out the yummy stuff. The inside of that balloon is called the spongocoel. Coel means cavity, so the giant empty space inside a sponge is a sponge cavity. WebbThe _____ is the central cavity in the simple sponges. Spongocoel.
