There's a fungus that turns ants into "zombies" - Apparently.
Ophiocordyceps unilateralis, a fungus found in tropical rainforests, infects ants and manipulates their behavior to ensure its own survival. The fungus grows inside the ant's body, eventually killing it, but not before causing it to climb to a high location and bite onto a leaf, creating an ideal environment for the fungus to produce fruiting bodies and disperse its spores. This phenomenon has been observed and studied in various regions, including the rainforests of South America and Southeast Asia.
