Parasitism is a relationship between species, where one organism, the parasite, lives on or in another organism, the host, causing it some harm, and is adapted structurally to this way of life. [20] The parasite either feeds on the host, or, in the case of intestinal parasites, consumes some of its food.
The gemsbok (Oryx gazella), or South African oryx, is a large antelope in the genus Oryx.It is endemic to the dry and barren regions of Botswana, Namibia, South Africa and (parts of) Zimbabwe, mainly inhabiting the Kalahari and Namib Deserts, areas in which it is supremely adapted for survival.
Symbiotic bacteria are able to live in or on plant or animal tissue. In digestive systems, symbiotic bacteria help break down foods that contain fiber. They also help produce vitamins. Symbiotic bacteria can live near hydrothermal vents. They usually have a mutual relationship with other bacteria. Some live in tube worms.
Struthionidae (/ ˌ s t r uː θ i ˈ ɒ n ə d iː /; from Latin strūthiō 'ostrich' and Ancient Greek εἶδος (eîdos) 'appearance, resemblance') is a family of flightless birds, containing the extant ostriches and their extinct relatives.
The only known freshwater bivalve with a symbiotic relationship are in the genus Anodonta which hosts the chlorophyte Chlorella in the gills and mantle of the host. [41] In bivalves, photosymbiosis is thought to have evolved twice, in the genus Anodonta and in the family Cardiidae. [ 42 ]
The Somali ostrich (Struthio molybdophanes), also known as the blue-necked ostrich, is a large flightless bird native to the Horn of Africa. [4] It is one of two living species of ostriches, the other being the common ostrich. It was also previously considered a subspecies of the common ostrich, but was identified as a distinct species in 2014. [1]
Each symbiotic relationship displays a unique ecological niche, which in turn can lead to entirely new species of host species and symbiont. [ 3 ] It is particularly interesting that it took so long to discover the marine microbial symbiosis because nearly every surface submerged in the oceans becomes covered with biofilm , [ 6 ] including a ...
