A Pelagic Thresher Shark (Alopias pelagicus) gets close to the camera in Monad Shoal, Malapascua, Philippines.
Also known as Fox sharks, Threshers have distinctive large eyes for seeing prey in the deep, and long caudal (tail) fins that they use like a whip to stun groups of fish. These sharks are guaranteed to be seen on a daily basis in Monad Shoal at around 4am, when they rise from the deep to be cleaned by cleaner fish (as seen in the photo) at cleaning stations that are within recreational diving depths.
Threshers are particularly shy and skittish, and it took a lot of skill, patience, technique, and luck to get this photo. Conditions were very dark (430am) and this particular cleaning station was still quite deep at 37m (122ft). On top of that, underwater strobes weren't allowed as the sharks' eyes were very sensitive to light, as they usually hunted in the deep.
Sadly, these sharks and their impressive fins are usually hunted for shark fin
