This Animal Sleeps 10,000 Times a Day, Each Sleep Lasts Only 4 Seconds

The white-chinned penguin is one of the extreme sleep performers in nature, experiencing more than 10,000 micro-sleeps lasting up to four seconds each day, according to new research. This penguin, which lives in breeding colonies each containing tens of thousands of individuals, must remain vigilant against threats to their nests from predatory skuas and hostile neighboring colonies.

The result is that the sleep schedule of penguins is in a state between awareness and sleep, reaching 11 hours of sleep time each day. The researchers behind this study published their findings on December 30 in the journal Science.

"This illustrates well at what point sleep is limited by the process of natural selection,"

"The animals face a clear tradeoff between sleeping and its benefits while being unalert, and being awake but at the physiological cost of not sleeping. These penguins have found a way to gain the benefits of sleep while remaining alert to protect their eggs."

The researchers studied the sleep patterns of 14 penguins from a colony of 2,700 breeding pairs on King George Island, off the coast of Antarctica. After surgically implanting electrodes into the penguins' brains and connecting them to data loggers on their backs, the researchers released them back to the island.

"After weeks of observing sleeping penguins, scientists have conclusive evidence of one of nature's most bizarre zonk strategies: hatching penguins experience 600 micro-sleeps every hour, each lasting an average of four seconds."

"By monitoring the brain activity of sleepy birds during their microsleeps, researchers also found that sometimes they only sleep with half of their brain, while the other hemisphere remains alert."

Want to Research the Sleep of Other Animals.

Scientists say that the unusual sleeping habits of chinstrap penguins challenge many dominant assumptions about sleep across the animal kingdom. Their next step is to look for other animals with strange sleeping patterns.

"Proving that sleeping this way costs nothing for penguins will challenge the current fragmented interpretation that is inherently detrimental to sleep quality,""
"Vladyslav Vyazovskiy and Christian Harding, penguin sleep researchers from Oxford University."
