Nature example of biological warfare

In the animal kingdom, the strong always prey over the weak. To some extend it is similar to our human society. Different creatures use different strategies to get their prey; the usual way is to be faster then the prey, like the usual lion chasing the deer. However some outsmart their prey, in this particular case this “amazing” creature done it by using biological “weapons”.
Ever heard about the komodo dragons, yes big large saurian lives in pockets of Indonesia’s islands. This creature are super clumsy, and as a small child I always wonder how this stupid creature kills, I always believe it is just some scavengers, like the T-rex, big with no grace. The cool fact about this creature it kills it’s pray by causing septicemia, an example of nature using biological weapons. Here is an extract form wikipedia:

“Komodo Dragons have not traditionally been considered venomous, but it has recently been suggested that they may produce weak venom. In addition to the possible venom, dragons also possess virulent bacteria in their saliva, of which more than 15 strains have been isolated. These bacteria cause septicemia in their victim; if an initial bite does not kill the prey animal and it escapes, it will commonly succumb within a week to the resulting infection. The lizard is able to locate its prey using its keen sense of smell, which can locate a dead or dying animal from a range of up to 9.5 kilometers (6 miles).The Komodo dragon appears to be immune to its resident bacteria.”

So good news to us, at least we Homo sapiens won’t be on its menu, we can always hope and depend on our so-call advanced medical therapies.
