An archaeon from deep-sea hydrothermal vents, Methanopyrus kandleri, has been grown in the lab at 122°C, under high pressure that keeps water from boiling. It is the highest temperature known at which any living thing can multiply. At that heat your proteins would cook instantly; its own are stabilized by special molecular architecture.
In 2022, a young tagged bar-tailed godwit flew from Alaska to Tasmania in about 11 days of nonstop flight, covering 13,560 km without eating, drinking or landing. Before departure, these birds pile on huge fat reserves and shrink their digestive organs, which are useless during the journey.
