Most sponges are filter feeders, which means they feed passively by consuming microscopic plant and animal life from the water. Since the animals are really about 66 percent empty space, they can intake enormous amounts of water. Adult sponges live on substrates or solid surfaces in aquatic environments. A few species can contract their whole bodies. This process is called gemmulation and it allows a degenerating or ding adult to release small clones that might fare better in the unfavorable conditions. In the tropical waters off the coasts of Florida, the Bahamas and Caribbean, shallow water sponges are common sights on reefs. The only time a sponge moves is when it has broken off of the parent sponge, and is floating through the water trying to find it's spot.
