Update on trimethylamine N-oxide (TMAO) as a piezolyte and cryoprotectant: its role in a depth limit for marine fishes and loss from hadal fish during capture by Paul Yancey (14354982)

“…In the ocean hadal zone (below 6000 m), snailfish from the Kermadec (Yancey et al. 2014) and Mariana trenches (Linley et al. 2016), and several amphipod species including <i>Hirondellea gigas</i> (Downing et al. 2018), confirmed a highly linear trend in TMAO contents down to the greatest ocean depths at which these animals have been found (< 8,400 m for fish, ~11,000 m for amphipods). …”
