What is the range of orcas?
They range from California to Russia and live in large groups. Four populations of Resident killer whales occur in the Pacific Northwest: Southern Residents.
How far do orcas migrate?

How far can orcas Echolocate?
500 feet
Echolocation allows killer whales to detect fish at distances of up to 500 feet, much farther than they could see in the dark water.
How long do Orcas live in the wild?

While those in the open ocean are called mammal-eating “transient” killer whales – they regularly travel several hundred miles hunting for seals, sea lions, and other large mammals. An adult orca consumes 100-300 pounds of food a day, depending on the animals size and energy needs.
Are there any orcas that do well in captivity?
