There's a fungus that turns ants into "zombies" - Apparently.
Ophiocordyceps unilateralis, a fungus found in tropical forests, infects carpenter ants and controls their behavior, causing them to climb to high locations and bite onto a leaf before producing spores that can infect other ants. This fungus essentially turns the ants into "zombies" to help spread its own spores. Studies have confirmed the fungus's ability to manipulate ant behavior, and it has been observed in various locations, including in the rainforests of South America.
