The Deep Sleeper
10 – 15 hours a day
The sloth is commonly referred to as the world’s slowest mammal, and with good reason. Studies have revealed that the common sloth climbs at a rate of around 2 ½ meters per minute.
In line with this, it’s no surprise that the sloth gets some of the most sleep of all the animals on our list, averaging around 10 hours per day, which is considerably more than the average amount of a human gets. Interestingly, it’s reported that sloths in captivity get around double this, usually clocking in between 10 – 15 hours of sleep per day. To avoid threats from predators, sloths are typically found sleeping in trees, and often even sleep whilst hanging from branches.
