What is Diurnal?
Diurnal animals are animals that are active during the daylight hours and sleep at night. Although humans can train themselves to stay up through the night, it is natural for us to sleep at night and be awake during the day. Many nocturnal animals, (animals that sleep during the day and stay up at night), have adaptations that let them function in the dark. The tarsier shown at the top of the poem is from the Philippines and has the largest eye to head ratio of any animal- these large eyes helps them see better at nighttime when they are active.
