Which animal has the most extended period of sleep?

While sleep is essential for most animals' survival, the amount of sleep and the pattern of sleep varies from one animal to another. Some animals are known to have long sleep periods than others, and the longest-sleeping animal is the brown bat.

The brown bat is known to sleep for more than 19 hours a day. That means it spends around 80% of its day sleeping. Brown bats are nocturnal animals, which means they are active at night and sleep during the day. The long hours of sleep help them conserve energy during the day when they are not active.

The amount of sleep an animal requires can depend on various factors, including their size, age, and lifestyle. For example, larger animals tend to sleep less than smaller ones, and animals that are active for more extended periods tend to sleep more.
