The Killer Whale or Orca is the biggest member of the dolphin family.
It has the ability to track down its prey using echolocation and can chase down victims at speeds of up to 65 km/h (40 mph).
Groups of killer whales occasionally hunt co-operatively, forcing prey such as shoal of fish into shallow water to be caught more easily.
Orcas have even been known to breach the surf and snatch seals and other animals from the beach.
