In further proof that evolution can yield some seriously spooky creatures, we bring you the candiru, a.k.a. the ‘vampire fish.’ This little happy camper from the Amazon lives as the name implies of blood, and can swim up your urethra to insert spikes in your bladder. Unfortunately there is no oxygen in the human bladder, so it dies while lodged in there. Unless you get surgical help very quickly indeed, you will die in searing agony.
Note to self: Never ever pee in water. No matter whether it’s the Amazon or elsewhere. Just don’t.
