Deep in tropical jungles, a fungus called Ophiocordyceps does something so creepy that scientists still find it hard to believe. Its spores land on an ant, sprout, and grow inside the antโs body. As the fungus takes over, it hijacks the antโs behaviour. The infected ant abandons its colony, climbs up a plant, and bites down hard on a leaf vein.
There the ant dies, jaws locked in place. The fungus then sprouts a long stalk out of the antโs head and rains spores down onto the forest floor - perfectly positioned to infect more ants below. Each Cordyceps species specialises in one specific kind of insect host.
This nightmare creature is what inspired the video game and TV series โThe Last of Us.โ Luckily for us, real Cordyceps canโt infect mammals. Our bodies are too warm and our immune systems are too different for the fungus to take hold. Lucky us.
