The '''[[Imperial Trans-Antarctic Expedition]]''' (1914–17), also known as the '''[[Endurance]] Expedition''', is considered the last major expedition of the Heroic Age of [[Antarctic]] Exploration. Conceived by Sir [[Ernest Shackleton]], the expedition was an attempt to make the first land crossing of the Antarctic continent. After the conquest of the [[South Pole]] by [[Roald Amundsen]] in 1911, this crossing remained, in Shackleton's words, the "one great main object of Antarctic journeying"." The expedition failed to accomplish this objective, but became recognized instead as an epic feat of endurance.

The Orca is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. Killer whales have a diverse diet, although individual populations often specialize in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals such as seals and dolphins. They have been known to attack baleen whale calves, and even adult whales. Killer whales are apex predators, as there is no animal that preys on them. Killer whales are considered a cosmopolitan species, and can be found in each of the world's oceans in a variety of marine environments, from Arctic and Antarctic regions to tropical seas.
