A “ghost fish”, belonging to the Aphyonidae family has been seen and captured on camera for the first time. Every times fishes of this family have been found, was by accident while dredging or trawling. None of these fishes were found alive and not much is known about this. This particular fish was spotted by the NOAA (National Oceanic and Atmospheric Administration) ship Okeanos Explorer during expedition of the Mariana trench. The fish is 4 inches long and it has blank eyes, scaleless exterior and transparent skin.
It has been a matter of debate among marine biologists if fishes of this species leave at the bottom of the sea or in water columns. Finding this fish 2,500 meters below surface makes biologists believe they might leave at the bottom. Bruce Mundy, NOAA fishery biologist said, “Some of us working with the fish have a wish list, you know, sort of a bucket list of what we might want to see, and a fish in this family is probably first on this list for a lot of us. This is just remarkable.”
