What is the largest species of shark?

The ocean's most colossal fish, the whale shark, holds the impressive title of the largest shark species, and indeed the largest fish on Earth. These magnificent creatures can reach lengths of over 60 feet (18.8 meters) and weigh up to 30 tons, making them longer than a school bus and heavier than several elephants. Despite their monumental size, whale sharks are gentle giants, posing no significant threat to humans.

Unlike their more predatory shark relatives, whale sharks are filter feeders. They cruise through tropical and warm-temperate waters with their enormous mouths agape, which can be over 5 feet wide, sifting vast quantities of water for their diet of plankton, krill, fish eggs, and small schooling fish like sardines and anchovies. Their specialized gill pads efficiently trap these tiny organisms, allowing the water to pass through. This unique feeding strategy allows them to sustain their immense bodies as they migrate thousands of miles across tropical oceans.

Each whale shark possesses a distinctive pattern of light spots and stripes on its dark grey skin, much like a human fingerprint, making every individual identifiable. These highly migratory animals can be found across the world's tropical oceans, except for the Mediterranean Sea, and are known to live for 80 to 130 years. Sadly, despite their docile nature, whale sharks are currently listed as an endangered species, facing threats primarily from targeted fishing, bycatch in other fisheries, and collisions with large ships.
