The Balistes Capriscus used to be a sub-tropical fish, but with global warming, it can be seen in Britania in summer time.Triggerfish have sharp teeth and powerful jaws that can crush apart things like crabs, spiny lobsters and sea urchins. They even produce noise when they grate their teeth together. But their powerfull jaws also make them partialy responsible for the beautifull white sand beaches: in Madagascar they feed mainly on coral, crushing the stony shells and extracting the polyps. But once digested, their droppings consist mainly of that famous white sand! Up to 200 pounds per year for a fish.
