5. If we had to name one of the animals most dangerous to humans, we would no doubt nominate wolves, bears or snakes. However, reality can be found behind a pair of tender-looking eyes. In comparison to any other animal, the whitetail deer is the species that inflicts the most harm on humans, because of all the traffic accidents they cause.
4. Speaking of faces that can be deceiving, there is another animal that is very dangerous. The actual estimate of annual human deaths due to sharks is 10; however, 100 more people die each year from being stepped on by cows.
3. Death is a reality of life and it has been proven that all mammals produce almost one billion heartbeats before dying. The mouse produces close to one billion, but its life cycle is just 850 days. The elephant has about 75 years through which to spread out those heartbeats. Humans are the exception. They are the only mammals that have a triple amount of heartbeats during a life cycle.
2. They say sharing is a way of life and perhaps some animals have taken this statement to extremes, like for example the prairie dog. The largest known colony was registered in the state of Texas in the United States. It was 160km wide, 402km long, and with 400 million inhabitants.
1. If this number is impressive, there is another that is even unpronounceable. In reality there are 10,000,000,000,000,000,000 insects on planet Earth. If this is incredible, more surprising still would be to find out who took count!
The rest up to number 50, here
