You're hiking in the woods with a friend one evening when a wind kicks up and rain starts to pour down. Suddenly you realize your friend isn't with you anymore. You shout, but your voice gets lost in the storm. Humans and animals both communicate in many ways. Humans use almost 6,000 spoken, written, and code languages and also depend on body language , sight, touch, and smell to relay messages.
Animals communicate with many sounds, actions, and cues as well.
Dolphins, toothed whales, and porpoises depend on vocalization , echolocation , and ultrasound to communicate with each other and navigate. Each key on the keyboard had a word written on it, and each key had a related cubbyhole containing an object that represented the word. Humans activated the keyboard by touching a key. Dolphins activated it by inserting their beaks into one of the cubbyholes. Inside each cubbyhole was an infrared beam.
