The Smallest fish in the world has apparently been just discovered. The scientist talking about it here is hoping we get a chance to discover it before it's habitat dies out:
The tiny, see-through Paedocypris fish have the appearance of larvae and have a reduced head skeleton, which leaves the brain unprotected by bone.
They live in dark tea-coloured waters with an acidity of pH3, which is at least 100 times more acidic than rainwater.
'This is one of the strangest fish that I've seen in my whole career', said Ralf Britz, zoologist at the Natural History Museum.
'It's tiny, it lives in acid and it has these bizarre grasping fins. I hope we'll have time to find out more about them before their habitat disappears completely.'
You're worried about us running out of acid water and acid rain? I don't think that's going to happen anytime soon dude, swim free little fish, swim free, we'll get to work on making you plenty more acid water to thrive in!
