Divers helped rescue two bullhead sharks ensnared in a discarded fishing line. Miguel Paula and Ludgero Silva swam to the scene armed with a divers knife to try and free the stricken sharks off the coast of Dukhan, Qatar. They had spotted the two sharks tangled in an old, barnacle and seaweed ridden fishing line which still had hooks attached. The duo, along with professional videographer Fernando Mateus, had been snorkelling in the idyllic spot before being alerted to the sharks plight. And the trio immediately set off to try and free the creatures.
