A whale shark has been filmed appearing to feed by scrounging around on the bottom of the ocean — the first time this behavior has ever been documented in this giant fish.
Whale sharks (Rhincodon typus) are the biggest species of shark on Earth, growing up to 60 feet (18 meters) long. They live in warm waters all over the world, though their population has likely decreased by more than 50% over the past 75 years. This new observation highlights how much scientists still don't know about the behavior and ecology of this threatened species.
