Orcas or Killers Whales are found in all the oceans of the world. They are a truly amazing animal to witness in the wild. They are actually not a whale at all but are actually dolphins. There are three different types of Orca, the resident pods which feed primarily on fish, transients which move long distances in a short period and feed on fish, and other marine mammals, also the lesser known offshores which also will feed on marine mammals as well. They have a varied diet though, there has been remains of rays in the stomach of one individual. Orcas form tight families within their pods. The males are the ones with the large(up to 6ft.tall)dorsal fins. Researchers identify each individual by their dorsal fin and the gray area just behind it called the saddle.
