We humans are awake during the day and sleep at night, but not all animals are on the same schedule as us. Animals of all shapes and sizes, from fireflies to possums, mice to leopards, have adapted to a life after dark.

At night, it’s harder to see, so many nocturnal animals rely on their other senses or have big eyes, like owls, to help them see in low light. But despite the drawbacks, there are lots of advantages to being nocturnal too. Some animals, like lions, hunt at night, giving them an advantage over prey that sleep at night and can’t see well in the dark. On the flip side, other animals like rodents are often more active at night in order to avoid predators that could catch them during the day. For some animals, being active at night allows them to save energy on hot days– lots of desert animals sleep during the day and wake up at night when it’s cooler. Even some desert flowers only bloom at night to avoid excessive heat and sunlight!
