Toucans manage their body temperature by adjusting the blood flow to their beak as more blood means more heat release. Due to this, the creatures sleep on their beak to conserve heat.

Lions enjoy relaxing and lazing around. They spend between 16 and 20 hours each day resting and sleeping. They have few sweat glands so they wisely tend to conserve their energy by resting during the day and become more active at night when it is cooler.
