Anyway, on one of the Seaworld websites they have a live camera in the tank viewing the orcas. Depending when you go to view them, you may see them swim by a lot or sometimes never at all. I've seen them swimming in the tank a few times. Orcas actually belong to the Dolphin family being the largest of them and most attractive. The Bull's dorsal fin is much larger and taller than the female's.
Orcas live in cool waters, esspecially polar regions.
They are found in all seas including the Western Mediterranean, Arabian Sea and the Gulf of Aden. Many of them are found off the west and northern coasts of Canada. The largest population seems to be in Antarctica where it is estimated some 160,000 animals range. Whaling has been increasing rapidly and whale populations are decreasing. Norway and Japan are esspecially bad for this.
