Australia has an ant which eats poisonous spiders in the outback. A few years ago it started killing and eating small animals even kangaroos. Scientists say the ant has evolved to have the same poison spiders have. Recently the ants have killed about 60 cows in farm land and police have found two men who were dead being eaten by this ant with the ants poison in their body.
