The orca, also called the killer whale, is the largest member of the dolphin family, found in oceans worldwide from polar to tropical waters, easily recognized by its black and white coloration and tall dorsal fin, which can reach nearly two metres in adult males. Orcas are highly social, living in matrilineal pods with complex vocal dialects that differ between populations, and different populations specialize in different diets, some hunting fish almost exclusively while others prey on marine mammals such as seals and even other whales, making the orca an apex predator of the ocean. Despite being widespread, some regional populations are small and declining due to pollution, prey depletion and human disturbance, and the species as a whole is classified as data deficient by conservation assessments.

threat (MediaWiki batch-API article extract states it plainly)
Some local populations are threatened or endangered due to prey depletion, habitat loss, pollution (by PCBs), captures for marine parks, and conflicts with fisheries.
system (MediaWiki batch-API article extract states it plainly)
A cosmopolitan species, it inhabits a wide range of marine environments, from Arctic to Antarctic regions to tropical seas, but is more commonly documented in temperate or cooler coastal waters.
