-The '''[[Antarctic midge]]''' is a species of flightless midge, endemic to the continent of [[Antarctica]]. At 0.079–0.24 in long, it is the largest purely terrestrial animal on the continent, as well as its only insect. It also has the smallest known insect genome as of 2014, with only 99 million base pairs of nucleotides (and about 13,500 genes).
+The '''[[southern elephant seal]]''' is one of the two species of elephant seals. It is the largest member of the clade Pinnipedia and the order Carnivora, as well as the largest marine mammal that is not a cetacean. It gets its name from its massive size and the large proboscis of the adult male, which is used to produce very loud roars, especially during the breeding season.
-This species is the [[National Symbols of Westarctica|national insect]] of [[Westarctica]].
+The world population was estimated at 650,000 animals in the mid-1990s, and was estimated in 2005 at between 664,000 and 740,000 animals. Studies have shown the existence of three geographic subpopulations, one in each of the three oceans. Tracking studies have indicated the routes traveled by elephant seals, demonstrating their main feeding area is at the edge of the Antarctic continent. While elephant seals may come ashore in [[Antarctica]] occasionally to rest or to mate, they gather to breed in subantarctic locations.
-To adapt to the cold temperatures, the Antarctic midge accumulates trehalose, glucose, and erythritol. These compounds help the insect survive freezing by reducing the amount of ice that forms within the body. They also stabilize proteins and membranes, binding to them by means of hydrogen bonds. Heat shock proteins also help the tolerance to both high and low temperatures.

-It not only tolerates, but also requires a freezing climate to survive: exposure of larvae to mild temperatures as +10 °C is enough to kill them within a week. Exposure to temperatures of +30 °C kills individuals in a few hours. It can, however, resist partial desiccation, surviving the loss of up to 70% of body water.
