Jako the white-collared lemur

Born in March at the Linton Zoo in the U.K., Jako the white collared lemur is already monkeying around. The young and mischievous lemur is quite energetic and playful, according to ZooBorns.

Not only is this little primate incredibly cute and comical, but his birth is also an accomplishment for the zoo — there are only 13 white collared lemurs in captivity in Europe, and nine of them live at the Linton Zoo.
