Facts on Sharks
Lets put some light on some facts about Sharks:
Large sharks are known to target the smaller, younger sharks since they are an easy target.
A 70 million year old piece of shark poop proved that baby turtle was the food of at least some ancient sharks.
Hammerhead sharks which have oddly shaped heads have electrical sensors which make them superior hunters.
People who do underwater photography should be aware of the fact that cameras emit electrical signals which sharks can mistake as food.
It is a wrong assumption made by people that sharks can smell blood, however sharks can't smell blood until blood reaches their nostrils.
There is approximately 4000 species of sharks. Sharks come in different shapes and size. The largest shark the whale shark has an approximate length of 59 feet and the smallest shark has a length of about 8-9 inches.
Sharks have around 5 to 15 rows of teeth in each jaw. But the rarity is that there is no root to these teeth so they fall out within a week and are replaced by a new set within a day.
Sharks have a very long life span. The whale shark which is the largest shark can live upto 60 years. The smaller sharks generally live up to 30 years.
It is a common mistake to believe that sharks are ruthless man eaters. In reality out of all the species, only 10 are man eaters.
The fact is humans are a bigger threat to shark than sharks are to human. Sharks are threatened by fishing which results in the death of thousands of sharks every year. In comparison, only ten people are killed every year by shark attack.
