Since Trieste's historic descent, a robot called Kaiko has explored more of the hadal zone, discovering a fragile, floating world of jelly life, insubstantial organisms that are able to exist only because the water is so still that currents don't tear them apart.    From Wordnik.com.  [Where Wonders Await Us] Reference

And they were not the first to pass this way, for from the time that mammals returned to the sea over 40 million years ago, the bodies of whales have been drifting into the hadal world, and a whole ecosystem has evolved around exploiting these unpredictable windfalls.    From Wordnik.com.  [Where Wonders Await Us] Reference
