The Collection was started in the 19th century; it consisted of preparations from Africa, Australia and South America, although most of the exhibits were actually from the surroundings of Dubrovnik, near or far. Today a lesser number of exhibits is in existence, of which the most noteworthy are the otter, Lutra lutra, caught in Zaton, the Mediterranean monk seal, Monachus monachus, taken in Molunt, and the right lower part of the jaw of a Balaenoptera musculus, blue whale, from the Bay of Bisvay.
