Deep sea trawling is also harming the biodiversity by destroying deep sea habitats which can take years to form. [34] Another human activity that has altered deep sea biology is mining. One study found that at one mining site fish populations had decreased at six months and at three years, and that after twenty six years populations had ...
Kagoshima Bay (鹿児島湾, Kagoshima-wan) also known as Kinkō Bay, Kinko Bay (錦江湾, Kinko-wan) is a deep inlet of the East China Sea on the coast of Japan. [1] Kagoshima Bay is on the south coast of the island of Kyūshū.
For the deep-sea ecosystem, the death of a whale is the most important event. A dead whale can bring hundreds of tons of organic matter to the bottom. Whale fall community progresses through three stages: [32] Mobile scavenger stage: Big and mobile deep-sea animals arrive at the site almost immediately after whales fall on the bottom.
Environments in which subsurface life has been found [1]. The deep biosphere is the part of the biosphere that resides below the first few meters of the ocean's surface. It extends 10 kilometers below the continental surface and 21 kilometers below the sea surface, at temperatures that may reach beyond 120 °C (248 °F) [2] which is comparable to the maximum temperature where a metabolically ...
An inlet is a (usually long and narrow) indentation of a shoreline, such as a small arm, cove, bay, sound, fjord, lagoon or marsh, [1] that leads to an enclosed larger body of water such as a lake, estuary, gulf or marginal sea.
The distinction between demersal species of fish and pelagic species is not always clear cut. The Atlantic cod (Gadus morhua) is a typical demersal fish, but can also be found in the open water column, and the Atlantic herring (Clupea harengus) is predominantly a pelagic species but forms large aggregations near the seabed when it spawns on banks of gravel.
The bathypelagic zone or bathyal zone (from Greek βαθύς (bathýs), deep) is the part of the open ocean that extends from a depth of 1,000 to 4,000 m (3,300 to 13,000 ft) below the ocean surface. It lies between the mesopelagic above and the abyssopelagic below.
Most deep sea pelagic fishes belong to their own orders, suggesting a long evolution in deep sea environments. In contrast, deep water benthic species, are in orders that include many related shallow water fishes. [71] The umbrella mouth gulper is a deep sea eel with an enormous loosely hinged mouth. It can open its mouth wide enough to swallow ...
