As picture perfect as Malapascua is, in a nation of 7,107 palm tree fringed islands, 2.5km long Malapascua wouldn’t be on anyone’s radar were it not for the thresher sharks that treat the island like a spa. Each morning as the sun peeks over the mountains on distant Cebu, Pelagic threshers rise from the depths to be cleaned by reef fish along a deep ledge known as Monad Shoal.

The fox shark, also called the common thresher shark, lives usually at depths of over 200 meters and it is sighted only rarely. This is the main reason, we don’t know very much about these animals, and there is very little good visual documentation showing thresher sharks up close on camera.

A diver had an oxygen toxicity seizure because an incorrect gas was filled in a cylinder by a dive centre. A baby died because the wrong dose of medication was injected. Who is to blame for the error and how do we try to make sure that these types of incidents aren’t repeated?

As Evelyn Bartram Dudas’s Nikonos III made its way toward the bottom of the Atlantic Ocean one day not too long ago, she did the only thing that made sense to her at the time. She dove after it, retrieving the camera just before it was lost amidst the twisted remains of a shipwreck on the sea floor. Her rapid descent cost her a broken eardrum.
