'''[[Charles Wilkes]]''' was an [[United States Navy|American naval]] officer, ship's captain, and explorer. The Exploring Expedition, commonly known as the "Wilkes Expedition," included naturalists, botanists, a mineralogist, taxidermists, artists and a philologist, and it was carried by USS ''Vincennes'' (780 tons) and [[USS Peacock|USS ''Peacock'']] (650 tons), the brig USS ''Porpoise'' (230 tons), the store-ship USS ''Relief'', and two schooners, USS ''Sea Gull'' (110 tons) and USS ''Flying Fish'' (96 tons).
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 [[Antarctica|Antarctic]] regions to tropical seas.


Departing from Hampton Roads on 18 August 1838, the expedition stopped at the Madeira Islands and Rio de Janeiro; visited Tierra del Fuego, Chile, Peru, the Tuamotu Archipelago, Samoa, and New South Wales; from Sydney sailed into the [[Southern Ocean|Antarctic Ocean]] in December 1839 and reported the discovery "of an [[Antarctica|Antarctic continent]] west of the [[Balleny Islands]]" of which it sighted the coast on 25 January 1840.

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.
