Babel Fish: a Alien Race from The Hitchhiker's Guide to the Galaxy
"‘The Babel fish,’ said The Hitchhiker’s Guide to the Galaxy quietly, ‘is small, yellow and leech-like, and probably the oddest thing in the Universe. It feeds on brainwave energy received not from its own carrier but from those around it. It absorbs all unconscious mental frequencies from this brainwave energy to nourish itself with. It then excretes into the mind of its carrier a telepathic matrix formed by combining the conscious thought frequencies with nerve signals picked up from the speech centres of the brain which has supplied them."
