Why are they nocturnal?
Nocturnal animals have evolved to thrive in the dark due to various reasons:
* Avoiding predators: Many prey animals are more vulnerable during the day, so they rely on the cover of darkness to hunt or find food.
* Hunting advantage: Predators can take advantage of the decreased visibility at night to ambush prey.
* Reduced competition: By being active at night, some animals avoid competing with daytime species for resources.
* Cooler temperatures: Nighttime temperatures are often cooler, which is beneficial for some animals.
* Specialized senses: Many nocturnal animals have heightened senses of smell, hearing, or sight, allowing them to navigate and hunt effectively in the dark.
