'''[[James Clark Ross]]''' was a British explorer of the [[Antarctica|Antarctic]] who, between 1839 and 1843, commanded an Antarctic expedition comprising the vessels HMS ''Erebus'' and [[HMS Terror|HMS ''Terror'']]; he charted much of the coastline of the continent. Between 1839 and 1843, Ross commanded HMS ''Erebus'' on his own [[Antarctic]] expedition and charted much of the continent's coastline. Captain Francis Crozier was second-in-command of the expedition, commanding [[HMS Terror|HMS ''Terror'']].
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.


In 1841, James Ross discovered the [[Ross Sea]], [[Victoria Land]], and the volcanoes [[Mount Erebus]] and Mount Terror, which were named for the expedition's vessels. They sailed for 250 nautical miles (460 km) along the edge of the low, flat-topped ice shelf they called variously the Barrier or the Great Ice Barrier, later named the [[Ross Ice Shelf]] in his honor. He was awarded the ''Grande Médaille d'Or des Explorations'' in 1843, knighted in 1844, and elected to the Royal Society in 1848.

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.
