A whale shark in Cenderawasih Bay, West Papua, Indonesia

Being gentle to the giants. International Whale Shark Day

Every year on August 30, ocean enthusiasts come together to draw attention to whale sharks and advocate for them. These gentle giants have been around for more than 240 million years, but the first specimen was discovered off the coast of South Africa in the 1820s. As the world's largest fish, whale sharks can grow up to 12 metres, with one reaching a record 18.8 metres. Found in tropical oceans around the world, these filter feeders glide through the water, mouth wide open, straining plankton and small fish. Each pattern on their dotted, starry skin is as unique as a human fingerprint. Sadly, the International Union for Conservation of Nature lists whale sharks as endangered due to overfishing, habitat loss and climate change. Amid adversity, there's hope, like in Cenderawasih Bay in Indonesia, a whale shark oasis that's pictured here. Here, these titans dine on the generosity of fishermen who feed them baitfish for luck, reflecting a unique bond between man and marine life.
