There is a dispute based on the taxonomy of the sailfish, and either one or two species have been recognized. [3] [4] No differences have been found in mtDNA, morphometrics or meristics between the two supposed species and most authorities now only recognize a single species, Istiophorus platypterus, found in warmer oceans around the world.
Range and habitat The Nile tilapia is native to larger parts of Africa , except Maghreb and almost all of Southern Africa . It is native to tropical West Africa , the Lake Chad basin, and much of the Nile system, including lakes Tana , Albert and Edward – George , as well as lakes Kivu , Tanganyika , and Turkana , and the Awash and Omo Rivers .
A marine habitat is a habitat that supports marine life. Marine life depends in some way on the saltwater that is in the sea (the term marine comes from the Latin mare, meaning sea or ocean). A habitat is an ecological or environmental area inhabited by one or more living species. [1] The marine environment supports many kinds of these habitats.
Physically formed by brown macroalgae, kelp forests provide a unique habitat for marine organisms [12] and are a source for understanding many ecological processes. Over the last century, they have been the focus of extensive research, particularly in trophic ecology, and continue to provoke important ideas that are relevant beyond this unique ...
The word "habitat" has been in use since about 1755 and derives from the Latin habitāre, to inhabit, from habēre, to have or to hold.Habitat can be defined as the natural environment of an organism, the type of place in which it is natural for it to live and grow.
Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms. [3]
The habitat is in the underwater hull of a floating structure. In the Sea Orbiter example this part should reach a depth of 30 metres (98 ft). The advantage of this type is horizontal mobility. Access shaft to the surface The habitat is accessible via a shaft to above the water surface. The depth of submersion is quite limited.
Habitat and ecology [ edit ] Halophilic Dunaliella species such as D. salina are notable for living all around the world in hypersaline environments such as salterns, salt lakes, and crystallizer ponds, with one unique subaerial species found growing on top of spider webs covering the walls of a cave in the Coastal Range of the Atacama Desert.
