Orcas (Killer Whales) Sleeping

Several members of the Orca (Orcinus Orca) family J Pod surface together to breathe while sleeping off Blakely Island in Washington's Puget Sound. When sleeping, the whales, also known as killer whales, turn off the half of their brains that are not responsible for regulating breathing. During this time, they tend to cluster, swim slowly in circles, and surface together.
