WASHINGTON D.C. - A sleepy sloth at Smithsonian National Zoo in Washington yawned for the camera in a super-cute video shared on May 30.
Footage by the zoo shows “serial chiller” Athena, a two-toed sloth, having a nap in her enclosure. According to the zoo, Athena can sleep between 15 and 20 hours day – but it is not because she is lazy.
“Sloths sleep to conserve the energy they get from their primary diet: leaves. While foliage does not provide a ton of nutrients, sloths’ very slow metabolism allows them to function on less,” it wrote alongside the clip.
