Echlocation
Echolocation - All dolphins can see, however as visibility is restricted underwater they have developed the use of a sonar system called  'echolocation' to find food when navigating and hunting for food. Their clicks make high-frequency sounds, and the echoes of these sounds bounce back which enables them to make a mental map. Using this mental map they are able to avoid the smallest of obstacles whilst locating their prey. In just a split second Echlocation enables them to determine the size of objects, their location, how fast they are
