The national animal of Scotland is not a real animal!

King James VI of Scotland succeeded Queen Elizabeth I of England, effectively uniting the two kingdoms. In a nifty symbolic move, James also chose to combine the royal arms into that of one united kingdom. The Scottish coat of arms had used two unicorns supporting a shield, and the English coat frequently depicted a lion in this regard.

Therefore, James decided to use both national animals in the new coat of arms, which was an especially powerful gesture considering that lions and unicorns were viewed to have been mortal enemies.

A flea can jump 30,000 times without stopping.

They can also jump 50-100 times their own body height. Also, a flea's acceleration when jumping is 50 times that of a space shuttle taking off!

A clock tower being constructed in Saudi Arabia is bigger than Big Ben.

The Royal Mecca Clock Tower is expected to be the world's second tallest building and the largest clock tower. Standing at a whopping 1,970 ft tall, it will be over SIX TIMES taller than the former title-holder and most recognizable clock, Big Ben in London. The clock faces on each of its four sides will also have a diameter of 151 ft, which is also a full 128 ft wider than Big Ben.

Upon completion, the clock will also boast 2 million LED lights on the clock faces and 21,000 green and white lights that will flash throughout each day to signal the Islamic call to prayer. Muslims are hoping that their clock tower will allow for the establishment of a new world timing standard or at least an alternative to Greenwich Mean Time in the UK.

A chameleon can move its eyes in two different directions at the same time.

This allows them to have a complete 360-degree range of vision around their body. When they locate prey, they can focus both their eyes in the same direction. This gives them excellent depth perception.

Counting to one trillion would take close to 542,241 years.

University of Houston professor Jim Granato stated that it would only take 31,688 years, but that would require you to spit out a number every second!!

You can certainly count to 10 in 10 seconds, but when we start to move onto really long polysyllabic numbers (like 52,375,127,348 for instance) it becomes much more difficult to keep up with 1 number per second.

Therefore, calculating how long it would take to count to a trillion (that's a million times a million) would require a more dynamic formula that takes into account the increased amount of time it takes to name the numbers as the numbers get higher. Our sources came up with a pretty good estimate of 542,241 years.

Either way, don't expect to count to a trillion in your lifetime.
