Pseudoliparis belyaevi is a species of snailfish found in hadal zone of the Northwest Pacific Ocean,[1] particularly the Japan Trench.[2]
In the Izu-Ogasawara Trench, south of Japan, a team of researchers from the Minderoo-University of Western Australia Deep Sea Research Centre and the Tokyo University of Marine Science and Technology managed to film the deepest record of a fish, the unknown snailfish species of the genus Pseudoliparis, at a depth of 8,336m (27,447 ft). The fish was recorded by an autonomous deep-ocean lander that was dropped from the DSSV Pressure Drop. [3]
A few days later, in the Japan Trench the team collected two fish in traps from 8,022m (26,319 ft) deep. This possibly breaks the depth record for a fish collected from the seafloor, previously held by Pseudoliparis swirei at a depth of 7,966m (26,135 ft). [4] These snailfish, Pseudoliparis belyaevi, may be the first fish to be collected from depths greater than 8,000m (26,247 ft) and have only ever been seen at a depth of 7,703m (25,272 ft) in 2008. [5] Another fish, Abyssobrotula galatheae, was trawled from the Puerto Rico Trench at a depth of 8,370m (27,460 ft). However, this specimen may have been caught using a non-closing net (a net that is open on the way up and down into the deep) and could have been retrieved at a shallower depth. [6][7]
Size
This species reaches a length of 10.8 cm (4.3 in).[1][8]
Habitat
The species is a marine and bathymersal fish that lives at depths exceeding 6,000m deep.[9] It is also harmless to humans.[1]
