Lemba is a remarkable chimp. Having suffered a polio attack when young, her legs are paralyzed. Even so, Lemba manages to move through the sanctuary with surprising agility – and at an impressive speed. In fact, Lemba likes nothing better than to climb the highest platform in her enclosure and watch the caregivers prepare meals! When the food is ready, Lemba makes sure to let all the other chimpanzees know that their meals are on the way!
