If it comes to keeping the common hippopotamus (Hippopotamus amphibius), one of the most important zoos in Europe is Ostrava Zoo in the Czech Republic. It is not only so because they have been keeping this species since 1967 without a break and 32 hippo calves were born there during this time, but also because the European Studbook (ESB) of this species has been kept here since 2006. Since the hippo is such a dominant species for Ostrava Zoo, it appears in the logo of the zoo since 2004. What’s more, the logo also appears in the design of the facade of the Tanganyika Pavilion, the home of the hippos. Besides all these, there is a hippo calf living in Ostrava Zoo at present, that, despite being more than a year old now, is still one of the favourites of the visitors of this Czech zoo.
