This video was shot during a dive in the Grevelingen (the Netherlands). I was filming this small jellyfish (about 5 cm) and suddenly it gave an amazing show! It was rotating, spinning and displayed a great light performance. I saw a lot of Jellyfish with lights but never with the rotation. Hope you like it.
