Yes, gorillas can walk like humans! Gorillas bipedal, or walk on their two feet, for a just few seconds and then resume walking on all fours as it’s generally more efficient with their shorter legs. But Ubuntu, or Ubu for short, has been caught strutting clear across our African Forest habitat! Researchers believe this unique characteristic of certain individual gorillas could be due to gathering food and/or not wanting to get their hands dirty or wet. | Jacksonville Zoo and Botanical Gardens
