We have five main sense organs - eyes, nose, tongue, ears, and skin. All animals share these five senses. The document then focuses on the powerful sense of smell of some animals like dogs, ants, moths, and mosquitoes. Dogs use their sense of smell to mark territories and find bombs or missing people. Ants and moths can locate food and mates from far away by smell. Mosquitoes find humans to bite based on the smell of our bodies. Certain animals like eagles and snakes also have enhanced senses of sight, hearing, and vibration detection to aid in hunting and survival.
