Description of Whales
Whales are described as any of the various numbers of marine mammals of the order Cetacea. The term cetacean includes all 76 known species of whales, dolphins, and porpoises.

Those more than 4 to 5 m (13 to 16 ft) long are generally referred to as whales, whereas smaller species are known as dolphins or porpoises. Whales have the general shape of a fish with forelimbs modified to form flippers, a tail with horizontal flukes, and one or two blowholes for breathing.

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.
