The orca is the largest member of the dolphin family Delphinidae, of the mammalian order Cetacea. It is often referred to as the killer whale because of its ferocious appetite; it is instantly recognizable thanks to its unique, bold black-and-white coloring. The orca inhabits more parts of the world than any other aquatic mammal, including every ocean, but most commonly in colder waters.

It is no surprise that indigenous peoples around the world revere the orca as a fearsome guardian of the sea, for at first glance it is a terrifying beast, with its huge glossy black body, round, blunt head and strong jaws lined with forty to fifty spiky teeth that are designed for tearing and ripping rather than chewing. They are also one of the fastest animals swimming in the seas, and can reach a speed of up to 30 mph in short bursts. Few animals are able to escape an orca when it is readying for its next meal.
