There’s nothing pygmy hippos love more than having plenty of sleep and long soaks in warm water. The pygmy hippo enclosure has been equipped with solar panels to make sure their hippo pond is always a nice temperature, ensuring these lovely hippos stay nice and warm all year long, even through the cold English winters.
Just like the giraffes, okapi, and warthogs, pygmy hippos hail from Africa. In fact, pygmy hippos are very rare animals and can only be found in West Africa. (Adapted from ZSL, London Zoo)
