white mostly on the bottom of their stomachs or lower surface, but can also be seen on other

parts of their bodies. Male whales have straight, tall (up to 6 foot) dorsal or fins, while females

have shorter (3 foot) sickle shaped dorsal fins. Killer whales have 46 to 50 cone-shaped teeth that

interlock and are used to tear and grasp. The Orca uses spyhopping ( a vertical position using tail

to keep it upright) to get a better view of its surroundings

Killer Whales or Orcas live in oceans all over the world. They mostly live in the cold, icy

waters approximately 52 degrees, this is cold enough to kill a person. But according to the basic

laws of geometry, an Orca has a smaller proportion of heat-dissipating, or heat scattering, skin

surface per unit of volume than a smaller body, allowing Orcas inch of fat or blubber

Unfortunately most almost 50% of the world population of Orcas live in captivity for health or safety reasons. And sometimes they spend out there entire life period in captivity. Scientists even added the captivity of Orcas to the list of habitats.

Orcas also use echolocation to navigate under water.
