The Louisville Zoo’s female baby pygmy hippo heard her name for the first time—Isoke (ee SO keh), which is African for satisfying gift. Isoke is thriving. She is brave and adventurous, even swimming by herself, without her mom by her side. But, she can still be found following in her mother’s footsteps quite often. There are only 50 pygmy hippos in 22 locations in North America and births are rare.
