Termites, although seemingly indistinct, are incredibly sophisticated in defense of their home. Some species have developed a unique defensive strategy in which they react to the vibrations caused by predators by hitting their heads rhythmically on the walls of their tunnels. This creates a low frequency vibration signal that spreads throughout the colony. This warning signal not only alerts other termites of the imminent danger, But it can also function as a distraction and deterrence for the predator itself.
