    Great water boatmen are
    large water insects. They are meat-eaters (known as carnivores)
    which eat other insects. Their backs are silver to camouflage
    them against the sky. This hides them from animals looking up
    at them from under the water. Great water boatmen can also fly
    to get from pond to pond!
