It is commonly known that animals have five main senses, touch, taste, smell, sight and hearing with the possible inclusion of balance. But is there really such a thing as having a sixth sense?
Most species of shark have sensors on the sides of their heads, which the sharks use to detect tiny muscle movements from creatures nearby. This "sixth sense" is known as electroreception and allows sharks to detect electromagnetic fields produced all animals.

For centuries now, it has also been questioned as to whether certain species of animal including rats, chickens, and snakes have the ability to detect earthquakes! These animals have to been known to leave earthquake zones up to days before the earthquake arrives, with this behavior also being displayed more recently during the devastating tsunami in southeast Asia in 2004 where there were very few wild animals harmed.
