A team of researchers in China has sequenced and assembled the high-quality reference genome for the Yap hadal snailfish, which was captured at a depth of 7,000 m in the Yap Trench in the western Pacific Ocean.
Hadal environments (depths below 6,000 m) are characterized by extremely high hydrostatic pressures, low temperatures, a scarce food supply, and little light.
Fish are the only vertebrates inhabiting the hadal zone, and hadal snailfishes have been found in at least five geographically separated marine trenches.
