Question

the blue dragons store their preys venom in their many fingers. they can then use that stored poison to defend themselves. so, never touch a blue dragon—unless you want to get a painful and possibly serious sting. blue dragons have another way to stay safe from predators. they float on their backs so their bright blue bellies point upward. the blue blends in with the water, making it hard for predators flying overhead to see them. and predators swimming below will have trouble spotting the dragons gray backs. the light color blends with the sunlight shining down through the water. this two - color effect is called countershading, and its a good way to avoid getting eaten! you might see blue dragons washed up on some beaches, but they usually drift on warm surfaces of the atlantic, pacific, and indian oceans. an air bubble in their stomach allows them to float for long periods of time. it is difficult for scientists to find these tiny creatures in the vast oceans. so, there is still much we dont know about them. what we do know, though, is that these beautiful dragons are full of surprising traits. based on the text, why are blue dragons dangerous? their sting is painful and can harm humans. they have razor - sharp teeth and sharp fingers. their strong fingers squeeze prey. they use weapons to catch food.
