THE WHALE SHARK FEEDERS 

Fishermen wearing Tan-awan Oslob Sea Warden Fishermen's Association (TOSWFA) t-shirts pray before the start of their working day in Tan-awan, Oslob in the Philippines island of Cebu, March 1, 2013. Tan-awan, in the southern Philippines island of Cebu, used to be a sleepy village that never saw tourists unless they were lost or in transit. Yet now they flock there by the hundreds - to swim with whale sharks, the world's largest fish. Whale sharks are lured to the Tan-awan coastline of the Oslob district by fishermen who hand feed them small shrimp, drawing divers and snorkelers to see the highly sought-after animals, known as gentle giants of the sea. But the practice has sparked fierce debate on the internet and among biologists, who decry it as unnatural. Picture taken March 1, 2013.
