of which a member of the very rare "mint" form is on display. Very admired among the visitors became thehollow tree trunk hosting death's head cockroaches (Blaberus craniifer) and females of the white-bandedtarantula (Acanthoscurria geniculata). Nonetheless, the artificial waterfall and small river stream is somethingthat attracts at the first glance, being exactly the place of living for the creature discussed earlier in the 2008Annual Report - the ocellate river stingray (Potamotrygon motoro), so far the only member of the cartilaginousfishes held in Ostrava. In 2009, the displayed stingray stock counting two animals was enlarged with five newindividuals arriving from Beauval Zoo (France). In addition, several medium-sized fish species native to fastmovingstreams of the Amazon region make a company to the stingrays.The world of water, still little known and mysterious to man, is to continue its expansion from the zoo'sbackground facilities to the visitor area and many species to be located in the planned Papua and Chitwanexhibits already found their new home behind the scenes. Nonetheless, endangered species continued to bethe focus of animal care personnel, with the critically endangered killifish (Pachypanchax sakaramyi), thevulnerable polleni cichlid (Paratilapia polleni) or the butterfly goodeid (Ameca splendens) extinct in the wildbeing the species that reproduced again in 2009.Facilities behind the scenes play a very important role in animal breeding, which for instance in the caseof the Elephant Jungle exhibit enabled the zoo adding new species that once had to grow up in minortanks under the keepers' control. This following a year break helped the zoo to recover the stock of thegiant pangasius (Pangasius sanitwongsei) placed amongst critically endangered species, with five younganimals released. A newcomer to the zoo, the silver shark (Balantiocheilus melanopterus) is another criticallyendangered species. Despite the very promising water dragon (Physignathus cocincinus) clutches, artificialhatching of eggs undergoing out of scenes failed to result in the breeding success in this Elephant Jungleexhibit dweller.It was not only the agama efforts what marked the evolving reptile breeding, which once did not have anygreater tradition in Ostrava Zoo: the out-of-scene animal management personnel was also successful to breedthe pond turtle (Emys orbicularis), Hermann's tortoise (Testudo hermanni), Madagascar day gecko (Phelsumamadagascariensis), as well as the East African spiny-tailed lizard (Cordylus tropidosternum). Constructionof several much-needed breeding vivariums behind the scenes also provided the opportunity to acquiredemanding and rare creatures to be ranging in the Papua exhibit under development, with especially theblue-spotted tree monitor (Varanus macraei) being an exceptional rarity. Papuan endemic species, this blackand blue arboreal animal is the first Ostrava Zoo's monitor lizard. A pair of these creatures was obtained fromPilsen Zoo, where they has managed reproduction and rearing of the species very well. Ostrava Zoo visitorsare to admire this new monitor lizard in the new exhibit in 2010.A very special success in breeding birds out of scenes is the first rearing of two male blue-winged geese(Cyanochen cyanopterus), a species endangered in the wild. Conversely, the long-term zero success in makingthe rare, endangered and sensitive white-headed duck (Oxyura leucocephala) reproduce is something thathas frustrated the zoo personnel. Although the species started hatching over time, efforts to achieve rearingstill has not met with success. Beside some other Anseriformes, offspring was successfully produced behindthe scenes in the pigeon species again, this in particular being the case of the rare Mindanao bleeding-heartpigeon (Gallicolumba crinigera crinigera) and Luzon bleeding-heart pigeon (Gallicolumba luzonica), with9
