World’s Smallest Fish
Last time I was deep sea fishing, I swear I caught one of these, but threw it back because it seemed a little small. God dammit... if only I knew it was fully grown!
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.

I'm a boy... from San Diego, CA (USA). And I don't really have a whole lot else to say about myself.
