c.o.o.l. fact #4
A forest in the ocean can grow and disappear in a week.

c.o.o.l. fact #3
Deep ocean critters like Megamouth sharks and Gulper eels have huge jaws and mouths as wide as half their length. They have lips that glow in the extreme darkness of the deep ocean depths.

c.o.o.l. fact #2
Using a deep-diving submersible (Alvin), in 1977 scientists, including Rutgers Marine and Coastal Sciences' Director, Dr. Frederick Grassle, discovered life at the mid-ocean rift: giant tube worms, large clams and deep-sea fishes. According to accepted theories of the time, this was impossible. Bacteria and plant life (the source of food for other life) need light to convert nutrients into stored energy (a process called photosynthesis). But sunlight can't penetrate 2,400 meters to the ocean floor. It turns out, these newly discovered forms of bacteria use hydrogen sulfide (H2S) to produce food, a process called chemosynthesis.

c.o.o.l. fact #1
Scientists estimate that there are a least a million new species to be discovered in the deep oceans.
