First look at a dark realm
Researchers from the University of Aberdeen in Scotland discovered an unusual assortment of marine creatures while exploring the South Pacific's New Hebrides trench in 2013. Fish called cusk eels, and bright red prawns, dominated the community, though they are rare in other deep marine trenches.
