Whilst out on training dives 13 & 14 Iain filmed this box jellyfish at White Rock, the float measuring just 2cms, these fascinating jellies have a square-shaped float with tentacles streaming from the corners of the bell. Like all box jellies they can sting using nematocysts, tiny stinging cells that line the other surface of the animal. When an animal touches the box jellyfish, the nematocysts fire, puncture the victim and eject venom. The venom paralyzes and kills the box jelly’s prey, which are usually invertebrates. There are 28 known species,only three can be fatal to humans - These live in the Gulf of Mexico, Japan and Australia.
