TL;DR Summary

Scientists have recorded the deepest fish ever on camera, a snailfish swimming at a depth of 8,336m in the Izu-Ogasawara trench, south-east of Japan. The hadal zone, which extends from 6 to 11km, is a forbidding place, characterised by complete darkness, crushing pressure and near-freezing temperatures. Marine animals living in the hadal zone have adapted on a cellular level to enable them to withstand the oppressive conditions, including high concentrations of organic molecules called piezolytes, which stop their cellular membranes and proteins from being crushed under extremely high pressure.
