Which is the biggest shark species in the world?

The largest shark species in the ocean is the whale shark, which measures between 46 to 60 feet when fully grown. This shark has an average lifespan of 70 years and is known as one of the slowest-moving shark species in the world.

These sharks are filter feeders, which is why their main diet consists of plankton and other small fish. The sharks are most commonly spotted in warm or tropical oceans and get their name from their massive size, which is sometimes comparable to that of whales. Unlike most others, whale sharks are generally docile and will not attack human beings.
