Killer whales (orcas) are highly social: They travel and hunt in groups called “pods.”
An orca may beach itself to scare seals or penguins into the water, where pod members will attack them.
Orcas hunt animals as small as fish and as large as other whales.
An average orca tooth is 3 inches long and curved backward to help shred prey.
An adult orca may eat 500 pounds of food each day.
