What is the largest fish?

Whale shark is the largest fish. It grows up to 46 feet long (14 m), rivaling a humpback whale in size. Its mouth can open large enough to swallow a human whole. (Reflex, these gentle giants eat only pinhead-size plankton). As thick as the walls of a bank vault, whale sharks skin is six inches (15 m) deep – the thickest of any animals’ – and covered in constellations of yellow spots. Marine biologists photograph these spots to identify whale sharks. Like fingerprints, the spots are unique to each animal.
