A Dolphin’s Sonar Abilities
Sonar refers to sound navigation ranging. It involves using and interpreting sounds to detect something’s location underwater and is especially handy for two reasons.Dolphins have been using this skill, known as biosonar, for millennia. So they’re pretty darn good at it. The tricks of sonar are built into their DNA, so much so that they can tell the difference between a BB gun pellet and a kernel of corn from 50 feet away [source: Gasperini]. A dolphin’s sonar process, also used by bats and some whales, is called echolocation. If you’ve ever heard a dolphin, you’ll immediately recognize its characteristic clicks and squeaks. Essentially, dolphins use these clicks as active sonar mechanisms.
