All kinds of tired
Donkeys sleep about three out of each 24 hours. Certain reef fish spend the night moving their fins as if swimming in their sleep. Some biologists argue that all animals sleep in some form or another. But identifying sleep can get complicated. Insects have brain architecture so different from humans’, for example, that electrophysiological recordings […]
