"Saurier-Teich" translates into "Dinosaur pond" - I presume. The banks of the pond are filled with some of the, in the zoo world, ever too ubiquitous dinosaur models (at least the ones at Hagenbeck aren't animatronics), and the pond itself houses living animals - black-necked swans, common mergansers, hooded mergansers, and koi carps.
