Scientists have recently discovered as many as 16 new species of deep-sea fish that have a special feature that allows n to absorb 99.5 per cent of all light that strikes ir skin.   Similar to ultra-black Vantablack material, se fish absorb light very efficiently, so much so that even under bright light y appear a mere silhouette with features being discernable by human eye.

Scientists discover ultra-black light-absorbing fishes

According to reports, new research shows that special near-total light absorption feature of fish comes from an abundance of melanin in ir skin, in dition, melanin which is same pigment present in human skin in order to protect us from sunlight, is arranged in a very special way. Some of se fish that possess this special ability and were part of study are fangtooth, pacific black dragon, anglerfish and black swallower among ors.

As per reports, study shows that melanin present in fish’s skin is arranged into densely-packed compartments called melasomes. Thanks to ir size, positioning and shape, se clusters are extremely efficient in absorbing light. In dition to absorbing a lot of sunlight that falls on n, melasomes also redirect all sunlight y failed to absorb into neighbouring melasomes which n absorbs it.

This discovery is of great importance because by studying size shape and arrangements of melasomes scientists and researchers will be able to manufacture cheaper and more effective ultra-black materiel which can be used in optical techlogy, such as telescopes and cameras, and for camoufl.
