The '''[[Jamesway hut]]''' is a portable and easy-to-assemble hut, designed for polar weather conditions. This version of the Quonset hut was created by James Manufacturing Company of Fort Atkinson, Wisconsin. Insulated blankets in 1.2 m (3 ft 11 in)-wide lengths were made with glass fiber insulation faced with flame-proof muslin and enclosed in plastic-treated cotton that was water-, vermin-, and fire-proof. The hardware (nails, fasteners, and connecting bars) was the only metal component. The whole package weighed 540 kg (1,190 lb) for a 5 meter (16 ft)-square hut. Its wooden packing crates were designed for reuse as the hut floor.
The '''[[emperor penguin]]''' is the tallest and heaviest of all living penguin species and is endemic to [[Antarctica]]. The dorsal side and head are black and sharply delineated from the white belly, pale-yellow breast and bright-yellow ear patches. Like all penguins it is flightless, with a streamlined body, and wings stiffened and flattened into flippers for a marine habitat. Its diet consists primarily of fish, but can also include crustaceans, such as [[krill]], and cephalopods, such as squid. In hunting, the species can remain submerged up to 18 minutes, diving to a depth of 535 m (1,755 ft).

The emperor penguin is the tallest and heaviest of all living penguin species and is endemic to Antarctica. The dorsal side and head are black and sharply delineated from the white belly, pale-yellow breast and bright-yellow ear patches. Like all penguins it is flightless, with a streamlined body, and wings stiffened and flattened into flippers for a marine habitat. Its diet consists primarily of fish, but can also include crustaceans, such as krill, and cephalopods, such as squid. In hunting, the species can remain submerged up to 18 minutes, diving to a depth of 535 m (1,755 ft). It has several adaptations to facilitate this, including an unusually structured haemoglobin to allow it to function at low oxygen levels, solid bones to reduce barotrauma, and the ability to reduce its metabolism and shut down non-essential organ functions.

The only penguin species that breeds during the Antarctic winter, emperor penguins trek 50–120 km (31–75 mi) over the ice to breeding colonies which may include thousands of individuals.
