These man o' war are bigger than a Mer with poisonous tendrils longer than a schooner. Furthermore, they inflate themselves with a special gas so as to fly.
Blooms of Pythagrian man o' war are hazards for SkyKnights though, let me tell you dearies, they can also be vexing for surfaced WinderWave.
The gases these beasts use to stay aloft are flammable. I hear igniting a bloom of man 'o war is considered an act of aggression in the HighCourt.
