That really sucks.. I agree, the Komodo is sure to be a huge blow to the zoo. It obviously sucks when this happens to any animal, even people. I just always feel the worst for reptiles because they're literally kept locked up and prevented from any escape. My roommate was just telling me a story the other day about a buddy who had a boa that had been left at a vacation home for a couple days and in that time the home burned down. When they went back he found the snake in basically one big char inside the warped glass tank..
On the "bright side", at least only 3 were lost at the zoo. It could have been significantly worse, I'm sure..
