Researchers studying komodo dragons (Varanus komodoensis) at George Mason University discovered 48 previously unknown peptides in their blood that might have antimicrobial properties. Their findings were published in the Journal of Proteome Research. For the largest lizard, these peptides may help prevent the animals from getting infections from their own saliva, which is host to at least 57 species of bacteria. With this number of bacteria, it is easy to understand why…

The more prosaic answer seems to be that they utilize poison, not particularly surprising or trivia worthy for a reptile. But the truth is not always sexy.
edyong | May 18, 2009For the longest time, people believed that the world's largest lizard, the Komodo dragon, killed its prey with a dirty mouth. Strands of rotting flesh trapped in its teeth harbour thriving colonies of bacteria and when the dragon bites an animal, these microbes flood into the wound and eventually cause blood poisoning.
But that theory was contested in 2005 when Bryan Fry from the University of Melbourne discovered that a close relative, the lace monitor, has venom glands in its mouth. The discovery made Fry suspect that Komodo dragons also poison their prey and he has just confirmed that in…

The locals believe that the dragons are the reincarnation of their ancestors and townsfolk, and would leave offerings of dead meat at the jungle's edge to keep the massive predators at bay. About a decade ago, however, they were forced to stop by their own government working with the American non-profit, the Nature Conservancy. Now they're blaming these groups for a recent spate of Komodo dragon attacks (including the death by bone-…
