Osedax is a genus of deep-sea siboglinid polychaetes, commonly called boneworms, zombie worms, or bone-eating worms. Osedax is Latin for "bone-eater". The name alludes to how the worms bore into the bones of whale carcasses to reach enclosed lipids, on which they rely for sustenance. They utilize specialized root tissues for bone-boring.
Marine deep sea polychaetes under the genus Osedax will colonize at whale falls in many different oceans, using a symbiont that can digest the bones within the carcasses (Jones et al,2007) This earned them the common name of "boneworms," and they are speculated to be a keystone species of these types of environments due to lack of organisms in ...
Contributing between 1 and 10% of total ocean primary productivity, 200 species of coccolithophores live in the ocean, and under the right conditions they can form large blooms. These large bloom formations are a driving force for the export of calcium carbonate from the surface to the deep ocean in what is sometimes called “Coccolith rain”.
Dead diatoms drift to the ocean floor where, over millions of years, the remains of their frustules can build up as much as half a mile deep. [64] Diatoms have relatively high sinking speeds compared with other phytoplankton groups, and they account for about 40% of particulate carbon exported to ocean depths.
On the sea floor, these carcasses can create complex localized ecosystems that supply sustenance to deep-sea organisms for decades. [1] In some circumstances, particularly in cases with lower water temperatures, they can be found at much shallower depths , with at least one natural instance recorded at 150 m (500 ft) and multiple experimental ...
A rarely seen deep sea fish resembling a serpent was found floating dead on the ocean surface off the San Diego coast and was brought ashore for study, marine experts said. The silvery, 12-foot ...
The Atlantic Ocean is teeming with life, but for the first time researchers have discovered dead zones in these waters - areas low in both oxygen and salinity - off the coast of Africa. Fish can't ...
To map where oxygen could be low in the ocean as temperatures rise, a study looked back to the Pliocene, 2.6 million to 5.3 million years ago. NC State scientist looked back millions of years to ...
