Sharks could be more vulnerable to the fishing industry than was previously thought, research has revealed.
BBC News Reports:
Marine scientists led by Aberdeen University have discovered that the deepest oceans of the world appear to be shark free.
One possible reason could be due to lack of food.
Researchers warn that the findings mean all shark populations are within reach of human fisheries and could be at greater risk than was thought.
In a paper published on Wednesday – ‘The absence of sharks from abyssal regions of the world’s oceans’ – the international team of researchers report that sharks have failed to colonise at depths greater than 3,000m.
Sharks are found throughout the world’s oceans and it had been hoped new species would be discovered as exploration went deeper.
However, 20 years of exploration combined with analysis of records over the past 150 years, has convinced the scientists that the world’s oceans are 70% shark-free.
