New World's Largest Omnivore Weighs 42000 Pounds, Scientists Find.

The whale shark has been officially declared the largest omnivore in the world, after a recent study found that they also feed on plant matter, specifically Sargassum seaweed. Previously, the title was held by the Kodiak bear. Whale sharks are the largest fish in the ocean, growing up to 60 feet long and weighing over 41,000 lbs. They have few predators, but young whale sharks can be hunted by blue sharks, blue marlins, orcas, and white sharks. Despite their name, whale sharks are gentle and do not attack humans.
