We don’t think anyone is going to disagree if we say that animals are incredibly cool. Some can see things the human eye could never perceive, others can hear stuff we don’t notice and a few can smell more details about someone than we could glean from their biography. However there are some animals that simply stand out as incredible examples of intelligence, skill or simply great mojo; here are just a few of the most intense animal and plant species that exist in the worl, like the killer acacia tree.
According to a professor at Pretoria University, the Acacia trees emit ethylene into the air whenever antelopes start grazing on their leaves. This travels up to 50 yards, warning other trees that herbivores are in the area. Once the alarm signal is given, the trees start producing leaf tannin in quantities lethal to the antelopes.Link
The professor studying this phenomenon discovered it as he was looking into the death of around 3000 South African antelopes.
