Every organism, whether small or big, has acquired several defense mechanisms to protect itself from others. Africa’s wildebeest use big horns to protect themselves from lions during migration. Some microorganisms inhibit the growth of other microorganisms for their survival. Few species use camouflage to survive and pass on their genes to the future generations. In this video, caterpillars of an unknown species exhibit a very interesting method of defense. If a threat comes close to these caterpillars, few of them sense it as danger and start quivering and that prompts the entire group to start moving in co-ordination. This creates the illusion that the entire group is one giant organism instead of multiple smaller caterpillars and thus, prevents the predator from attacking.
