Once you reach depths of thirteen thousand feet, everything has a strange name but rarely a backbone: vampire squid and zombie worms, cosmic jellyfish, tripodfish and faceless cusks and pelican eels. Creatures that live this deep are frequently solitary and only infrequently seen. There are big things down here, old things, and certainly more of them than we know about. Almost every piloted dive to these depths has uncovered something new.
