These nighttime bandits can sleep up to 21 hours a day! Their diet of choice includes squirrels and mice, but prairie dogs make up the majority of it, which they hunt at night. (Prairie dogs are up most of the day looking for food.) The ferrets are also fossorial, meaning they live underground. And though they've come back from the brink of extinction, black-footed ferrets still need a lot of help. You can symbolically adopt one here!

Arthur must have been extraordinarily tired during school because aardvarks are nocturnal! Natives of Africa, they escape the harsh sun underground, which they burrow into using their claws that look like little spades, according to National Geographic. When the sun sets, they emerge and snuffle for termites (their favorite) using their long tongues.

Frilled lizards are diurnal, meaning they're active during the day. Though its armor makes it look like a reptile, the pangolin is actually a scaly mammal. Their scales are made of keratin, like your hair, and form a heavy-duty layer when they curl up into a ball to protect themselves. They're also one of the most trafficked mammals in Asia for their meat, but especially their scales, which are used in traditional remedies.

Two-toed sloths are so slow, it's probably best they hang out in the dark away from any potential threats. Believe it or not, they're actually great swimmers and can plunk into water and breaststroke their merry way to their destination. Coquerel's sifaka, a fun name to try and pronounce, are the opposite: They're springy lemurs named after the sound they make (shi-fakh, shi-fakh, shi-fakh!).
