Whales -
Echlocation
Echolocation - All
whales can
see, however as visibility is restricted underwater they have developed the use of a sonar system called
'echolocation' to find
their prey when navigating and hunting for food. The clicks of
whales 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 whales to
determine the size of objects, their location, how fast they are.
