Where do panguins sleep?

Answer 1

• Unlike humans, penguins never really fall asleep. Because they are often prey for predators such as leopard seals and Galapagos sharks, they have to constantly remain alert and on guard. Therefore, rather than going into a deep slumber like most other animals penguins take several short naps throughout the day. On average, these naps last only minutes. For added protection, penguins can usually be found sleeping in groups (or rather, a rookery, as a group of penguins is called). These close sleeping arrangements not only provide security, but also supply additional warmth for the already well-insulated bird species.
