This jellyfish also is called blue bottle and floating terror. Given the last nickname, I'm sure you know that this is a force to be reckoned with. It's blue tentacles can deliver a fatal sting.
It also has a sail that fills with gas and makes it float. The sail can be deflated allowing to submerge briefly.
