Chorisodontium aciphyllum is a species of moss found primarily on both sides of the Drake Passage.
 The species exhibits an extreme degree of cryptobiosis – the ability of a life form to enter a non-metabolic state, extending life indefinitely.
Yelovichnus is an "enigmatic" genus known from fossils of the Ediacaran period.
 "Yelovichnus" was originally believed to be an ichnotaxon: its fossils, because of their "meandering nature", were initially thought to be feeding trails left by other life forms, such as annelids or mollusks.
 Better-preserved specimens later demonstrated that the fossils were not true feeding trails, as there was no evidence of turning by the life form that supposedly left them.
 The fossils are now recognized as belonging to an organism taking the form of "collapsed, segmented tubes", possibly an alga or a protist.
 It has also been argued that "Yelovichnus" and similar organisms are xenophyophores, large but single-cellular organisms that exist today in the abyssal zone.
 Due to similar structures found in their fossils, it is theorized that "Yelovichnus" may be related to "Palaeopascichnus", as well as "Aspidella" and "Neonereites".
 The main difference between "Yelovichnus" and "Palaeopasicichnus" is the shape of their segments: the segments of "Yelovichnus" took the shape of "closed, ovate-shaped loops", whereas the segments of "Palaeopascichnus" were quite varied in shape.
Platystemon is a monotypic genus of flowering plants in the poppy family containing the single species Platystemon californicus, which is known by the common name creamcups.
 It is native to Oregon, California, Arizona, Utah and Baja California, and is found in open grasslands and sandy soils.
Rhodochiton is a genus of flowering plants within the family Plantaginaceae, native to southern Mexico and neighbouring Guatemala.
 They climb by means of twining leaf stalks.
 One of the three species, "Rhodochiton atrosanguineus", the purple bell vine, is grown as an ornamental plant.
 All three species are sometimes included in "Lophospermum".
Web Life is a concept, that proposes that the World Wide Web (Web) has, or could, evolve into an entity worthy of consideration as a life form in its own right; a new posthuman species consisting of just one isolated member.
In the fictional Buffyverse established by "Buffy the Vampire Slayer" and "Angel", a Demon is a kind of nonhuman life form separate from the animal kingdom.
Virus is a Dark Horse Comics comic book, written by Chuck Pfarrer, drawn by Canadian artist Howard Cobb and first published in 1992.
 The story is about an alien life form which takes over a Chinese research vessel and reconfigures it—using both the damaged electronics and the dead bodies of the crew, it propagates itself by making various "creatures" created out of both organic and inorganic parts.
 When a salvage ship shows up they have to deal with the life form or be taken over as well.
Synthetic mycoides refers to an artificial life form created by Craig Venter at the J Craig Venter Institute in May 2010.
 A synthetic genome was transferred into an empty cell to form the bacterium.
In biology, an organism (from Greek: οργανισμός, "organismos") is any individual entity that exhibits the properties of life.
 It is a synonym for "life form".
110 years prior to the series, Mayuri Kurotsuchi was an inmate in the Maggots Nest, the only one dangerous enough to be chained behind bars for his utter lack of regard for the life when it comes to experimentation.
 But that changed when Mayuri is visited by Kisuke Urahara and his lieutenant Hiyori Sarugaki, the former offering Mayuri a position in the SRDI.
 After initially refusing being Urahara's assistant, Mayuri accepts when Urahara points out that he be his successor should anything happen to him.
 Nine years after his release, Kisuke and Hiyori forced to leave the Soul Society, Mayuri becomes the new captain of Squad 12 as the result of the fifth experiment in his life-creating Nemuri Project while later taking the seventh surviving experiment, Nemu Kurotsuchi, to be his lieutenant and lab assistant while pretending to be uncaring towards her to hide his joy of creating a fully stable artificial life form.
 During this time, Mayuri experimented on Quincies, including Soken Ishida, the grandfather and trainer of Uryū Ishida.
