Dragon Fish : Scientists have discovered the secret behind the disappearance of the darkest fish in the ocean.

"I couldn't take a better picture," said Karen Osborne of the Smithsonian Institution.

Their detailed research on this fish has shown that this darkest fish is so black that its skin absorbs light.

This ability to absorb light also makes it difficult to photograph the fish, and marine creatures say that is why it is invisible and invisible.

Dr. Osborne says there is no way to avoid predatory fish in the deep seas, so its deep black color helps it not to be seen.

According to this research, many other deep black creatures have developed the same ability as this fish.
