Photo by Howard Hall

Whale sharks are grayish-brown with white spots and lines, and a white underside. Individuals are usually between 20 and 55 feet long making them the largest fish in the world. They are filter feeders that ingest plankton, fish, squids, and pelagic crustaceans as they open their very large mouths. Whale sharks are usually seen in open water, but occasionally spend time off of coral walls and steep slopes. They are found worldwide in tropical waters at depths to 100 feet.
