Question

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 clues in the text, why might it be difficult for scientists to find and study blue dragons in their natural environment? blue dragons are very hard to see floating in the large oceans. scientists have trouble studying creatures that float in water. blue dragons are shy creatures, so they hide from researchers. scientists are not sure which ocean blue dragons live in.

Explanation:

The text states that blue - dragons are tiny and float in the vast oceans, making them hard to see. There is no mention of scientists having general trouble with water - floating creatures, blue - dragons being shy, or uncertainty about which ocean they live in.

Answer:

Blue dragons are very hard to see floating in the large oceans.
