Seattle Zoo's website has a nice Komodo Dragon section, which opens with a nice Flash animation. The Zoo now has a permanent exhibit featuring two dragons, one 7.5-foot adult male; one 3-foot juvenile female. They are are on display in Woodland Park Zoo's Trail of Adaptations building.
And Tim Spalding's Komodo Dragon Central is a nice site with links to other zoos with Komodos, webcams and photo galleries.
