Orcinus is a genus of Delphinidae, the family of carnivorous marine mammals known as dolphins. It includes the largest delphinid species, Orcinus orca, known as the orca or killer whale. Two extinct species are recognised, Orcinus paleorca and O. citoniensis, describing fossilised remains of the genus. [2]
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. A cosmopolitan species, it is found in diverse marine environments, from Arctic to Antarctic regions to tropical seas.
Whales are a part of the cetacean family, which is divided into two groups: baleen whales (which don't have teeth) and toothed whales. These animals are found in every ocean, but this doesn't mean ...
Approving two proposed killer whale species could transform how they're conserved. It would also turn a new page in one of the strangest chapters in marine mammal history.
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).
Female orcas, like their human counterparts, live decades beyond their reproductive years.
Six species of dolphins have the word "whale" in their name, collectively known as blackfish: the orca, or killer whale, the melon-headed whale, the pygmy killer whale, the false killer whale, and the two species of pilot whales, all of which are classified under the family Delphinidae (oceanic dolphins).
