Why do whale sharks filter-feed instead of hunt like other sharks?
Quick Answer
Whale sharks feed on plankton and small animals because they are enormous, slow-moving filter feeders. Their wide mouths and filtering structures let them collect huge amounts of tiny prey.
The Full Story
Whale sharks are the largest living fish, and their feeding style matches their size and ecology. Rather than chase individual prey, they open their huge mouths and filter plankton, small fishes, and larvae from the water. Their gill rakers trap food as water passes through, allowing them to feed efficiently in plankton-rich areas. This strategy works especially well during seasonal blooms and fish spawning events. Their gentle feeding makes them very different from the predatory image many people associate with sharks.
