We’re leaving the Aquarium, but stay with the animals. Zoos are something we love to visit wherever we go. The zoo in Barcelona has the perk of having not one but two species of hippos, and I love hippos. These are the pygmy hippos, which are a solitary species, quite unlike the “normal” hippos who live in groups.
Something to keep in mind the next time somebody tries to tell you about human behaviour because of chimps or something.
