Ocean Exploration Facts
Snailfish in the family Liparidae was filmed at a depth of 1,365 meters (4,480 feet).

What is the deepest-living fish?

The deepest confirmed fish sighting is of a snailfish filmed at a depth of 8,336 meters (27,000 feet) below the ocean surface.
The image features a collection of deep-sea creatures arranged against a black background. The arrangement includes various species of fish and small marine animals, each with distinctive features. In the upper left corner, there's a large fish with a round body and dark eyes, accompanied by a bright orange-red shrimp. To its right, another shrimp displays long, luminous blue appendages. Below, a slender, elongated fish with a slightly shiny body is positioned horizontally. The center of the image showcases a large shark-like creature with a streamlined body and prominent fins. On the right, a thin, vibrant blue fish extends vertically with noticeable fins. At the bottom left, a bulbous-headed fish is oriented towards the viewer, flanked by smaller shrimp, while a fish with a long, pointed snout swims nearby. On the bottom right is an elongated fish with reflective scales.
