by The chinstrap penguin (Pygoscelis antarcticus) is a species of penguin that inhabits a variety of islands and shores in the Southern Pacific and the Antarctic Oceans.
Its name stems from the narrow black band under its head, which makes it appear as if it were wearing a black helmet, making it easy to identify
Chinstrap penguins are generally considered to be the most aggressive and ill-tempered species of penguin.
Chinstrap penguins microsleep over 10,000 times a day and accomplish this in 4 second bouts of sleep.
The sleep can be both bihemispheric and unihemispheric slow-wave sleep.
The penguins accumulate over 11 hours of sleep for each hemisphere daily.
