How long and how much does the whale shark weight?

Whale sharks are the largest fish species, typically measuring between 40 to 60 feet (12 to 18 meters) in length, though some individuals can grow even larger, up to about 65 feet (20 meters). They can weigh between 15 to 30 tons (approximately 13,600 to 27,200 kilograms). Their massive size and gentle nature make them a fascinating subject of study in marine Biology.
