Over the last few decades, as wild orca research has expanded, researchers have described different forms or types of orcas. Known as ecotypes, these distinct types of orcas differ in size, appearance, prey preferences, foraging techniques, dialects, behaviours, and social groups.

The orca (Orcinus orca), or killer whale, is a toothed whale and the largest member of the oceanic dolphin family. It is the only extant species in the genus Orcinus and is recognizable by its black-and-white patterned body.

Orcas or killer whales have a cosmopolitan distribution and several distinct populations or types have been documented or suggested. Three to five types of orcas may be distinct enough to be considered different races, [1] subspecies, or possibly even species [2] (see species problem).

The killer whale, also known as orca, is the ocean’s top predator. It is the largest member of the Delphinidae family, or dolphins. Members of this family include all dolphin species, as well as other larger species, such as long-finned pilot whales and short-finned pilot whales, whose common names also contain "whale" instead of "dolphin."

2024年11月25日 · Also known as killer whales, orcas (Orcinus orca) are one of the world's most effective and versatile predators. Although they are marine mammals and cannot walk on land, they are even known to manipulate animals from terrestrial areas into the sea for hunting.

Orcas, or killer whales, are the largest of the dolphins and one of the world's most powerful predators. They're immediately recognizable by their distinctive black-and-white coloring.

Over the last few decades, as wild orca research has expanded, researchers have described different forms or types of orcas. Known as ecotypes, these distinct types of orcas differ in size, appearance, prey preferences, foraging techniques, dialects, behaviours, and social groups.

Did you know that orcas (killer whales) are the largest member of the dolphin family? With their distinctive black and white patterning and huge dorsal fins, a pod of orcas powering through the waves is one of the most impressive sights in the natural world.

Scientists divide orcas into three types: 1) residents, who stay close to shore in a given area, prey mostly on fish and are relatively easy to approach and study; 2) transients (Bigg's Orcas), who live in smaller grounds range over a large area and feed mostly on seals, sea lions, dolphins and other marine mammals; and 3) offshore, those who li...

Found in every ocean on the planet, orcas are likely the most widely distributed mammal in the world, next to humans. There are three distinct types of orcas recognized in the eastern North Pacific Ocean—transient, resident, and offshore. Residents live close to shore in large pods of about 10 to 20 individuals and feed primarily on fish.
