Distribution:
Also known as a blue button, is actually a colony of different types of polyps. Each polyp is specialised for defence, reproduction or catching food. They feed on plankton, using stinging tentacles to kill their pray. They use gas filled tubes to keep themselves afloat and the right way up in the water.
