My head is filled with random facts of God knows what. People always seemed amazed by the pointless knowledge so I started putting them down on my facebook on Fridays. Then I decided why not have somewhere to post them for others to share and see on days besides Fridays.

SHARKS!!! SHARKS!!! SHARKS!!!
Sharks are so highly adapted for swimming and hunting that they have very specialized skin made up of microscopic teeth called "Dermal Denticles" meaning skin teeth. These 'teeth' are designed to reduce drag by up to 8% pointing back towards the tail (similar to dimples on a golfball). They also reduce turbulence which makes sharks undetectable by microphones or other fish when cutting through the water.
