Ant colonies build whole cities underground, and that little anthill on the sidewalk is only the front door. Ant tunnels can reach anywhere from a few feet to more than 10 feet deep, depending on the species. Ants dig twisting tunnels and hidden chambers to protect their food, their babies, and their queen. Thousands of ants move through these tunnels using pheromone trails as road signs. One Argentine ant supercolony in southern Europe even stretches about 3,700 miles across thousands of nests. Explore how carpenter ants, weaver ants, and red wood ants each build a different kind of home. If you want to learn more, check out @KiwiCo at kiwico.com/YTShorts #ants #antcolony #science #kiwico
