As with all toothed Whales, Orcas emit high-frequency sounds, and receive echos to navigate in their environment and locate prey. This highly developed form of sonar is called Echolocation and provides data that the whale is then able to translate into information of the surrounding world. Echolocation enables whales to navigate through even the darkest ocean depths.
Sound clicks are produced in the blowhole and focused as a beam through their melon. Echos are received through the lower jaw to their ear bones and form an acoustic image. Although Orcas use this sophisticated Echolocation system to navigate and catch prey, they also have very good eyesight.
