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.
