Scotoplanes globosa, commonly known as the sea pig, is a species of sea cucumber that lives in the deep sea. [1] It was first described by Hjalmar Théel , a Swedish scientist. Scotoplanes globosa , along with numerous other sea cucumbers were discovered by Théel during an expedition on HMS Challenger between the years of 1873-1876.
Scotoplanes (and all deep-sea holothurians) are deposit feeders and obtain food by extracting organic particles from deep-sea mud. Scotoplanes globosa has been observed to demonstrate strong preferences for rich, organic food that has freshly fallen from the ocean's surface [ 7 ] and uses olfaction to locate preferred food sources such as whale ...
Orthopristis chrysoptera are found at depths between 1 and 20 m (3 ft 3 in and 65 ft 7 in), [1] where they can be found in estuaries and bays, sometimes entering canals, but seldom waters of very low salinity. Within these shallow waters they inhabit a range of habitats, residing over soft substrates such as sand or silt, hard substrates ...

Most water in Earth's atmosphere and crust comes from saline seawater, while fresh water accounts for nearly 1% of the total. The vast bulk of the water on Earth is saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.
Hydrophis platurus, the yellow-bellied sea snake, is the only one of the 65 species of marine snakes to spend its entire life in the pelagic zone. It bears live young at sea and is helpless on land. The species sometimes forms aggregations of thousands along slicks in surface waters.
Fresh water falling as mist, rain or snow contains materials dissolved from the atmosphere and material from the sea and land over which the rain bearing clouds have traveled. The precipitation leads eventually to the formation of water bodies that humans can use as sources of freshwater: ponds , lakes , rainfall , rivers , streams , and ...
Copepods are a group of small crustaceans found in ocean and freshwater habitats. They are the biggest source of protein in the sea, [24] and are important prey for forage fish. Krill constitute the next biggest source of protein. Krill are particularly large predator zooplankton which feed on smaller zooplankton.
