Sharks have what you could call a special attribute they have a sixth sense. Sharks use the small canals that pepper their face to detect electricity from a wide area. This helps them to find their next meal or even a mate. Also, the sharks have special coloring. The grayish part of their backs helps them to camouflage with the grayish sandy ocean floor (if you were looking from the top of the water that is). The white-is coloring on their bellies helps them to camouflage with the bright water or sunlight
