Anaerobic Bacteria
An anaerobic organism or anaerobe is any organism that does not require molecular oxygen for growth. It may react negatively or even die if free oxygen is present. In contrast, an aerobic organism (aerobe) is an organism that requires an oxygenated environment. Anaerobes may be unicellular (e.g. protozoans, bacteria) or multicellular. Most fungi are obligate aerobes, requiring oxygen to survive. However, some species, such as the Chytridiomycota that reside in the rumen of cattle, are obligate anaerobes; for these species, anaerobic respiration is used because oxygen will disrupt their metabolism or kill them. Deep waters of the ocean are a common anoxic environment. First observation In his letter of 14 June 1680 to The Royal Society, Antonie van Leeuwenhoek described an experiment he carried out by filling two identical glass tubes about halfway with crushed pepper powder, to which some clean rain water was added. Van Leeuwenhoek sealed one of the glass tubes using a flame an ...

Spinoloricus
''Spinoloricus'' is a genus of nanaloricid loriciferans. Its type species is ''S. turbatio'', described in 2007, and another species, native to completely anoxic environment, '' Spinoloricus cinziae'', was described in 2014.Neves, Gambi, Danovaro & Kristensen (2014) ''Spinoloricus cinziae'' (Phylum Loricifera), a new species from a hypersaline anoxic deep basin in the Mediterranean Sea.''
