There are over 300 species of Snailfish. While many live in shallow waters (tidepools) and river estuaries, some have adapted to the cold water, as well as the high-pressure depths of the world's deepest trenches over 7,000m. [8] In general, the snailfish (notably genus Pseudoliparis) is the most common and dominant family in the hadal zone. [4]
It is apparently the top predator along certain stretches of the Mariana Trench, feeding on tiny crustaceans in a deep-water habitat with few larger predators. [4] Pseudoliparis swirei are abundant in their deep-sea habitat and lay relatively large eggs that are almost 1 cm (0.4 in) in diameter.
An unknown snailfish species of the genus Pseudoliparis was filmed in the Izu-Ogasawara Trench, south of Japan, at a depth of 8,336m during a two-month long expedition. ... The world's deepest ...

Species of deep-sea snailfish have been studied and compared to other ray-finned fishes (also known as teleosts) to analyze their adaptions to deep-sea conditions. The genomes of both the Yap hadal snailfish and Mariana hadal snailfish have been found to contain an abundance of the fmo3 gene, which produces the trimethylamine N-oxide (TMAO) protein stabilizer.
Pseudoliparis amblystomopsis, or the hadal snailfish, is a species of snailfish from the hadal zone of the Northwest Pacific Ocean, [1] including the Kuril–Kamchatka and Japan Trenches. [ 2 ] In October 2008, a team from British and Japanese institutes discovered a shoal of Pseudoliparis amblystomopsis at a depth of about 7,700 m (25,300 ft ...
They have been observed swimming at extreme depths of 8,336 metres (27,349 ft; 5.180 mi), in very deep ocean trenches of the Pacific Ocean, [4] [5] including the Izu-Ogasawara Trench and the Mariana Trench.
The deepest area at the plate boundary is the Mariana Trench proper. ... In May 2017, an unidentified type of snailfish was filmed at a depth of 8,178 metres (26,800 ...
