The Orca breaths by jumping out of the water, every few minutes. An Orca calf is full grown from between 8 months to 2 years. The Orca family stays together till they die. The Orca whale is mostly found in the Poles, but have been found as far away as the tropics. Baleen are teeth like and used like a sieve.
Echolocation is when a whale sends sounds out that bounce off objects.
When they bounce off objects the whale can find out how many feet away it is from the object. The Orca whale has teeth, not baleen like most whales. The Orca can have up to 48 large conical teeth. Even though most whales that live in the Poles have baleen the Orca has teeth and lives in the Pole too. Most of the Orca's weight is mussel.
