Purple Cup Sponges

I think these are called pipe organ sponges, and for a good reason. Some can reach as much as six feet tall, and perhaps as much as a foot across. The deep purple color, especially underwater, is striking, and offers a nice backdrop to small creatures that love to live inside the cups.
