When the first Komodo Dragons came to zoos, they were certainly considered rarities-and like tame "Moritz" in Berlin, some even became local "favourites". But being "just" big lizards, they were not that famous and popular for the public as Giant Pandas, although they often shared the same task as a "political gift" (like the ones given to former German Chancellor Helmut Kohl in the 1990s, one of the first Komodo Dragons I ever saw). And I remember various older zoo husbandry books claiming how hard it is to breed them...
Dozens of documentaries on the BBC, Discovery Channel, Animal Planet as well as various hatchlings later, this all has changed: now the term "Komodo Dragon" is well-known to the TV-watching public, and with improved breeding success (and as Chester's "Flora" seems to prove, even parthenogenesis is a possibility), they become more and more common-at least in American zoos, where they are still the big stars in every herpetological collection.
Two things make me wonder, though:
1) Why does it take the Komodo Dragons so long to "conquer" the European zoos? Maybe because the name of the species isn't that catchy in some of the Non-English languages: "Dragon" does sound better than "monitor"...

At the moment, about 16 European institutions keep, and some even them-and yet big zoo countries like Germany have to wait for theirs; the Germans at least till Leipzig opens its Gondwana Hall...
2) Given the fact that in some of the US federal states (and some European countries) one can get almost everything and anything as a pet, I'm surprised that I have only once heard about a privately kept Komodo Dragon. Not that I advocate it, but their absence strikes me as particular, given their popular status among reptile fans, who otherwise keep everything, may it be Ethiopian mountain adders or Angonokas...
