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.
Pelagic zones. The ocean can be conceptualized as being divided into various zones, depending on depth, and presence or absence of sunlight.Nearly all life forms in the ocean depend on the photosynthetic activities of phytoplankton and other marine plants to convert carbon dioxide into organic carbon, which is the basic building block of organic matter.
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 ...
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 ...
Every spring, an area appears when the water doesn't have enough oxygen to support fish and other marine life.
Sediment layers in these cores reveal the deposition patterns of the ocean over time. Scientists use paleo-oozes as tools so that they can better infer the conditions of the paleo oceans. [ 9 ] Paleo-ooze accretion rates can be used to determine deep sea circulation, tectonic activity, and climate at a specific point in time.
The two primary types of ooze are siliceous, which is composed primarily of silica (SiO 2), and calcareous or carbonate, which is mostly calcium carbonate (CaCO 3). [1] In an area in which biogenous is the dominant sediment type, the composition of microorganisms in that location determines to which category it is classified.
The scientific term for a dead zone is called hypoxia, which in Latin means "too little oxygen." Hypoxia occurs when less oxygen is dissolved in a body of water. Nearly all animals need oxygen to ...
