Sharks are really fascinating creatures! Feared by mankind for their fierce eating habits and their vicious look, but still are we so intrigued by this majestic creature. The following are a few interesting things about sharks you may not know -

• There are more than 360 shark species.
• Sharks don’t always bite, just sometimes. Unlike humans sharks can not eat continuously in a row, so most often they bite to determine if the object is worth their digestive time. If they’ve bitten it and don’t think it is worth their while they will leave it and find something better. It is almost like us people inspecting a menu deciding what to eat.
• According to experiments it has been concluded that sharks may be afraid of dolphins.
• It is possible for female sharks to reproduce and give birth without having any physical contact with a male shark. Not always, but sometimes. One particular case has been documented of a female shark not having had contact with a male shark in three years, but has given birth to a baby shark without any parental DNA present; resulting in the newborn almost being an exact replica of his mother.
• In some cultures sharks are worshipped as gods.
• Sharks are said to have been living on earth for 400 million years.
• When a shark dies its cartilage dissolves and its teeth drop to the bottom of the ocean where it is covered with sandy sediment which prevents oxygen and destructive bacteria from reaching the tooth and that is why when you find a shark tooth fossil it is grey, black or brown and not white of colour.

Now whether you are fascinated by the shark specie, fear them or are just intrigued with them, the above facts should help give a little insight to this incredible creature.
