Deep-sea ultra black fish
Karen Osborn, Smithsonian Institution

One specimen of the ultra-black fish species Anoplogaster cornuta. This fish was so lively after being sampled and documented that the research team released it back to the deep via submarine the day after being caught in a trawl net.

In the July 16 issue of the journal Current Biology, a team of scientists led by Smithsonian’s National Museum of Natural History research zoologist Karen Osborn and Duke University biologist Sönke Johnsen report on how a unique arrangement of pigment-packed granules enables some fish to absorb nearly all of the light that hits their skin, so that as little as 0.05% of that light is reflected back.
