Question

How do we know that the animals have six sense of smell?

Answer 1

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 electro-reception 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."
