by Hannah Waters In August 1994, Mandy Joye dove to the deep sea in a submersible for the first time. A newly-minted Ph.D., she had recently completed her graduate studies on marine microbes living...
Thousands of seamounts—most of them undersea volcanoes—tower above the muddy seafloor. They provide something hard to come by in the deep ocean : a solid surface to cling to. This photo gallery shows...

Found in Arctic waters, this rare deep-water species of larvacean , Oikopleura gorskyi , eats by filtering particles from the seawater it drifts through. Larvaceans build 'houses' around themselves...
It is a well-known fact that for animals living in the deep sea, food can be scarce. The food that is around usually rains down from above as dead animals and organic particles from plankton living...
