The Berlin Zoo is a treat for kids and adults alike. It is the biggest and most popular zoo in all of Germany. Lying in the centre of the city, the zoo was home to Knut, a polar bear and BaoBao, a panda, both of whom have now passed away. Today the zoo houses hundreds of species of animals such as lions, kangaroos, ostriches, bears, koalas, giraffes, elephants, boas, etc. The animals are kept in sections that are designed to resemble their natural habitat and there are several interactive exhibits. The Berlin Aquarium is a part of the Zoo but can be accessed separately too. A large variety of fishes, crocodiles, etc. can be seen here.
