All of these jellyfish photos were taken in the wild and come from all over the world. No namby pamby aquarium shots here. Australia has many jellyfish but in the tropics the ones everyone worries about are the box jellyfish and the Irukandji. They can be absolutely deadly especially to young children. Thankfully something as simple as a lycra stinger suit or even pantyhose can provide enough of a barrier from the tentacles to save your life. So when the water starts to warm up, you would be absolutely mad if you didn’t wear something.
Thankfully good old white vinegar can cause the tentacles to release and stop injecting their toxins so if you are crazy enough to swim on the beaches in northern Australia, make sure you have some readily available.
