Why do jellyfish sting? | Greg Foot | Head Squeeze

You're in the sea swimming around like you just don't care, and all of a sudden a jellyfish approaches you and stings you, why did they do it and what can you do to stop that pain?

Well jellyfish use their sting to capture prey and act as a defence mechanism. When their tentacles encounter a human or other sort of prey they reach out and fire out a neurotoxic venom. It will paralyse their prey but in the case of us lowly humans it will just really hurt.

Also, just an FYI, peeing on a jellyfish sting will not make it any less painful. So if a friend offers to help you can kindly tell them thanks but no thanks.
