In photos: Swimming with jellyfish

Beautiful pictures of amazing creatures …

… but on a point of order re. the biology, “Since the jellyfish in the lake have no natural predators, they have lost their sting” is misleading and wrong.

Jellyfish don’t have “sting” to ward of predators – they still get eaten freely by turtles, whales and others. They “sting” in order to paralyse THEIR prey, generally small fish. And without SOME kind of sting, they would simply starve and die. Even if that string cannot penetrate human skin.
