In zoology, deep-sea gigantism or abyssal gigantism is the tendency for species of deep-sea dwelling animals to be larger than their shallower-water relatives across a large taxonomic range. Proposed explanations for this type of gigantism include necessary adaptation to colder temperature, food scarcity, reduced predation pressure and ...
Detection of SIS stimulates the giant clam to swell its mantle in the central region and to contract its adductor muscle. Each clam then fills its water chambers and closes the incurrent syphon. The shell contracts vigorously with the adductor's help, so the excurrent chamber's contents flows through the excurrent syphon.
The Clipperton fracture zone is the southernmost of the north east Pacific Ocean lineations. It begins east-northeast of the Line Islands and ends in the Middle America Trench off the coast of Central America, [4] [11] [6] forming a rough line on the same latitude as Kiribati and Clipperton Island, from which it gets its name.
The abyssal zone or abyssopelagic zone is a layer of the pelagic zone of the ocean. The word abyss comes from the Greek word ἄβυσσος ( ábussos ), meaning "bottomless". [ 1 ] At depths of 4,000–6,000 m (13,000–20,000 ft), [ 2 ] this zone remains in perpetual darkness.
Continental shelves teem with life because of the sunlight available in shallow waters, in contrast to the biotic desert of the oceans' abyssal plain. The pelagic (water column) environment of the continental shelf constitutes the neritic zone, and the benthic (sea floor) province of the shelf is the sublittoral zone. [35]
The world's exclusive economic zones by boundary types and EEZ types. An exclusive economic zone (EEZ), as prescribed by the 1982 United Nations Convention on the Law of the Sea, is an area of the sea in which a sovereign state has exclusive rights regarding the exploration and use of marine resources, including energy production from water and wind.
The Euxine abyssal plain is a physiographic province of the Black Sea, an abyssal plain in its central parts. Its name comes from the Ancient Greek name Euxeinos Pontos ( Εὔξεινος Πόντος ) of the Black Sea.
The Sohm Abyssal Plain is in the North Atlantic and has an area of around 900,000 square kilometres (350,000 sq mi). [1] It is located off the coast of the Canadian Maritime provinces and New England in the United States. [2] The region was named for Rudolf von Willemoes-Suhm, a German naturalist on the Challenger expedition in the late-19th ...
