Tarsiers are primarily nocturnal animals, which means they are most active during the night. Their physical and behavioral adaptations are well-suited to low-light conditions, making them highly efficient nocturnal hunters. During the day, tarsiers typically rest and sleep, often in concealed locations within the forest canopy, such as tree branches or tree hollows.
Tarsiers have several adaptations for their nocturnal lifestyle, including large eyes with exceptional night vision, forward-facing eyes for binocular vision, and ultrasonic hearing capabilities. These adaptations help them locate and capture their prey, which primarily consists of insects and other small animals, in the dark.
While tarsiers are primarily nocturnal, their activity patterns can vary between species and individual circumstances. Some factors, such as food availability or the presence of potential mates, can influence their activity during the night. However, their nighttime behavior remains a defining characteristic of their biology.
