Today's interesting fact has to do with the Komodo dragon.

This very large lizard, lives on four main islands of Indonesia, Komodo, Rinca, Flores and Gili Motang.

It lives mostly on carrion, but also hunts and ambushes prey.

It is a very strong swimmer and has been found swimming more than six miles from land, and it has been suggested it may also catch and eat fish.

It was long thought that in ambushing large animals, a combination of bacteria in their saliva caused toxic shock in the attacked animals, which then incapacitated the animals, and allowed the Komodo dragons to finish their kills.

Recently, keepers of Bearded Dragon lizards, noticed that mice caught by their lizards died faster than expected. Someone did some study and noticed that these lizards had venom in their saliva and further study discovered they had venom glands. This prompted an expanded study, because up to that moment, the only venomous lizards were thought to be the Gila Monsters in the Americas. The study showed that Komodo Dragons, as well as many other lizards, also have venom glands, and this is what incapacitates the Dragons prey, not bacterial toxic shock.
