Ladies, did you know that there could be some shark in your lipstick? Supposedly, many cosmetics items such as lipstick, moisturizer and eye makeup could contain shark liver oil. Rather than the stomach, the liver happens to be the largest organ in the shark's body.

3. It's a shark eat shark world

Before entering into the underworld, it becomes a battle of the sharks in the womb.  This is known as oophagy and is most commonly found amongst sand tiger sharks. These baby sharks consume their siblings before even being born. It is survival of the fittest, the ultimate hunger games of the shark world. Not to mention, larger sharks may also prey on small species of shark.

5. Sharks have cleaner teeth than you

Besides being sharp and terrifying, sharks also have better dental hygiene than human beings. Sharks have a layer of fluoride coated over their teeth, making them insusceptible to cavities. Their cavity free, pearly whites could also be from constantly sinking their teeth into unsuspecting prey.

6. Sharks are the virgin Mary

Female sharks have the ability to have offspring without intercourse with a male partner. In this case, the embryo is able to develop without fertilization by sperm.  This freaky virgin birth is scientifically classified as Parthenogenesis, a form of asexual reproduction.
