Whale shark uses multiple feeding methods: The first is considered passive feeding, where the shark swims with its mouth open, continually collecting food as it goes. When food concentrations are high, the shark will use one of two suction-type feeding methods: One where the shark hovers vertically, nearly motionless. During these feedings, the shark will open and close its mouth, creating a strong suction, bringing in larger volumes of water download What a Fish Knows: The Inner Lives of Our Underwater Cousins pdf, azw (kindle), epub.
