The leopard coral grouper is highly-valued as a food fish and is sold in both the live and chilled reef fish food trade, centred on Hong Kong. The catching of live fish for export is an important commercial fishery in the Asia-Pacific region, currently they are primarily sourced from Indonesia and the Philippines. In Australia it is caught by ...
The General Bathymetric Chart of the Oceans (GEBCO) is a publicly available bathymetric chart of the world's oceans. The project was conceived with the aim of preparing a global series of charts showing the general shape of the seafloor. Over the years it has become a reference map of the bathymetry of the world's oceans for scientists and others.
Diaulula odonoghuei from Patrick's Point, CA. Diaulula odonoghuei, the spotted leopard dorid, is a species of dorid nudibranch found in the Pacific Ocean. [1] [2] Identified as a cryptic species in 2016, [3] it is differentiated from its sister species Diaulula sandiegensis by having considerably more spots on their mantle.
The pelagic food web, showing the central involvement of marine microorganisms in how the ocean imports nutrients from and then exports them back to the atmosphere and ocean floor. A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton.
The oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf (e.g. the neritic zone), but operationally is often referred to as beginning where the water depths drop to below 200 metres (660 ft), seaward from the coast into the open ocean with its pelagic zone.
The mesopelagic zone is important for water mass formation, such as mode water. Mode water is a water mass that is typically defined by its vertically mixed properties. [5] It often forms as deep mixed layers at the depth of the thermocline. [5] The mode water in the mesopelagic has residency times on decadal or century scales. [5]
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 ...
The thicknesses of the photic and euphotic zones vary with the intensity of sunlight as a function of season and latitude and with the degree of water turbidity. The bottommost, or aphotic, zone is the region of perpetual darkness that lies beneath the photic zone and includes most of the ocean waters. [1]
