Orcas are considered the largest species of the dolphin family. They weigh up to 6 tons (5,443 kilograms) and grow to 23 to 32 feet (7 to 9.7 meters).
Orcas are very social and live in groups called pods, which usually have up to 40 members.
Orcas are black and white for a reason; their coloring helps to camouflage them by obscuring their outline in the water.
