Zombie Ants!

Reading about zombie ants:

To find the world’s most sinister examples of mind control, don’t look to science fiction. Instead, go to a tropical country like Brazil, and venture deep into the jungle. Find a leaf that’s hanging almost exactly 25 centimeters above the forest floor, no more and no less. Now look underneath it. If you’re in luck, you might find an ant clinging to the leaf’s central vein, jaws clamped tight for dear life. But this ant’s life is already over. And its body belongs to Ophiocordyceps unilateralis, the zombie-ant fungus.
