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 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.
The genus Orcinus was published by Leopold Fitzinger in 1860, [4] its type species is the orca named by Linnaeus in 1758 as Delphinus orca.Taxonomic arrangements of delphinids published by workers before and after Fitzinger, such as John Edward Gray as Orca in 1846 and Orca (Gladiator) in 1870, are recognized as synonyms of Orcinus.
There are several distinct groups of orca populations, with habits and lifestyles different enough hat some scientists think that orcas should rightly be defined into several different species or ...
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.

The bottlenose dolphin is a toothed whale in the genus Tursiops.They are common, cosmopolitan members of the family Delphinidae, the family of oceanic dolphins. Molecular studies show the genus contains three species: the common bottlenose dolphin (Tursiops truncatus), the Indo-Pacific bottlenose dolphin (Tursiops aduncus), and Tamanend's bottlenose dolphin (Tursiops erebennus).
