Diana and I visited a coastal beach at Cape San Blas, Florida. I found several Portuguese Man-o-War which had washed up on the sand. They are often (incorrectly) thought of as jellyfish. But, they actually consist of several colonies of organisms which function together. Each of the colonies is so specialized in the function it performs that it needs the others in order to survive. The man-o-war lives at the surface of the warm water oceans with the air bladder that you see in this photo floating on the surface. The air bladder can be up to 10 inches long.
