Do the Orca in Antarctica differ from other Orca?
Genetically, very slightly. They are the same species, but there are very slight differences in appearance. There are three documented types of orca in the Antarctic and there are even slight differences among them. However, they are still the same species, like black and white humans.

Yes, orca dolphins can kill sharks. Orca dolphins are super predators that people usually call killer whales because orca dolphins are killer whales and they are killers of the ocean. Orca dolphins are the most powerful, dangerous and the deadliest predators on earth and they kill everything that lives in the ocean for food. Orca dolphins also kill other top predators as well.

All swimming mammals in this geography are confined to the Southern Ocean, which surrounds Antarctica. Leopard seals and Weddell seals can be seen sunning on Antarctica's beaches, however, during breeding season, with their pups. There are no land predators on the continent. Or you may be thinking of Humpback whales, orca whales, or other whales.
On earth, both south of the Antarctic Circle -- where you'll find the Antarctic continent -- and north of the Arctic Circle, depending on your exact location, you will experience at least one 24-hour period of no sunrise/sunset each year. Antarctica is as large as USA and Mexico combined, so numbers of days/ weeks/ months of no sunrise/sunset differ.
There are many animals in Antarctica such as; various types of penguins, (Emperor Penguins, Gentoo Penguins, Rockhopper Penguins and others) Petrels, ( Skua, Antarctic Tern, Sheathbill and others.) seals and whales including the Orca or Killer Whale. Polar Bears are NOT from Antarctica, they're from the Arctic (North Pole) not the South.
Orcas have no predators except for occasionally humans. No creature other than humans can kill the orca. The only possible way for a human to kill an orca is for the orca to be shot with a harpoon. Orca's are playful creatures, but when it comes to hunting, they'll kill anything as long as it won't kill them first, and the orca ALWAYS wins unless there is a harpoon.
