WebbThe average energy cost of thermoregulation (C th) for adult penguins was equivalent to 10–16% of basal metabolism. C th comprised about 15% of the estimated daily energy budget (DEB) of incubating adults, but only about 1% of the DEB of adults feeding chicks. The T e 's for chicks older than 14 days ranged from 0 to 31°C, averaging 8.0 C. Webb22 dec. 2010 · A major adaptation that allows penguins to forage in cold water is the humeral arterial plexus, a vascular counter-current heat exchanger (CCHE) that limits heat loss through the flipper. Fossil evidence reveals that the humeral plexus arose at least 49 Ma during a ‘Greenhouse Earth’ interval. ihsaa girls basketball sectional bracket
