Sponges are colonies of single-celled individuals organized into recognizable shapes with often unique colors. They can have many shapes: carpets, blobs, trees, vases, pipes and so on. Most sponges do not prefer to live in the intertidal and all like to be submerged most or all of the time. Sponges grow only slowly and most are not capable of competing with plants, so they are found in dark places and in deep water. Many sponges can grow very old.
