Male and female hyenas are hard to distinguish because they have similar-looking external reproductive organs. Female hyenas give birth to twins after a 3 to 4 month pregnancy. Although they often kill prey, they are also scavengers, eating dead animals that they find. Lions often steal kill from hyenas. Hyenas have powerful jaws and sharp teeth that they use to break open bones so thay they can eat the bone and marrow.
Hyenas can go without water for several days.
