Ghostly white and with broad wing-like fins and an eel-like tail, the unknown species of snailfish was recorded multiple times by cameras sent down to the depths. The deepest point of the trench was first discovered during the expedition of the Challenger in 1875, which recorded using drag lines a maximum depth at the time of around 8,184 meters (26,850 feet), towards the southern end of the canyon.

So the deepest depths of the oceans, while supporting some large organisms such as sea cucumbers and shrimp, are really dominated by the ubiquity of bacteria. But scientists think that this might be the limit at which fish can survive, meaning that the absolute depths of the Trench probably can’t support fish simply due to the constraints of the physiology of vertebrates.
