When I was diving in Australia off the Queensland coast, we all sort of lived in fear/awe of the Irukandji jellyfish – tiny, transparent jellyfish whose venom can kill purely from the extreme pain it inflicts. Worrying stuff indeed. Luckily, jellyfish stings find it hard to get through any sort of material so in our wetsuits we were relatively safe.
Now its seems more of us will be at risk from swarms of these jellyfish as they migrate around the world in search of food. In a new film, cinematographers trace the path of these surprisingly intelligent and well defended animals as they head away from their traditional areas and foray for new food sources. Beautiful but unnerving, this is one film everyone who dives (and swims) should probably watch.
