The Species of Denigma
Create and customize your creature from the five main species of Denigma: tiny yeast, elegant nematode, gracious fruit fly, ingenious mice, or the ferocious rats. o
Budding yeast
Saccharomyces cerevisiae (id = 4932)
The tiny budding yeast is a single-cellular eukaryotic organism which replicates via asymmetric cell division. It exhibits two forms of aging: one which limits its ability to produce daughter cells to around 20 cell divisions (replicative lifespan) and another one which determines how long it can stay in the stationary phase (i.e. without division; chronological lifespan).The tiny budding yeast is a single-cellular eukaryotic organism which replicates via asymmetric cell division.

Nematode
Caenorhabditis elegans (id = 6239)
The nematode is an elegant model organism. It is fully transparent and the developmental lineage and position of each cell can be followed. They are usually hermaphrodites (i.e. it is both male and female). The adult hermaphrodite comprises exactly 959 somatic cells. Genes can be selective silenced by feeding them with plasmids expressing siRNA constructs. Their lifespan is about 2-3 weeks, but they can entire an alternative development stage and become so called DAUERs (German for sustained/endurance/continuity). DAUERs do not age.

Fruit fly
Drosophila melanogaster (id = 7227)
The fruit fly is just about 3 mm in length. These species have predominant red eyes and are characterized by slow hovering flight in which their abdomen hangs down. Fruit flies as their name suggests love fruits, vegetables and fermenting liquids. The usual lifespan of a fruit fly is about 1 month.The fruit fly is just about 3 mm in length.

House mouse
Mus musculus (id = 10090)
The house mouse has its origin in Asia and arrived in Britain in the 10th century, brought on via shipping. Nowadays they are found throughout the world. They are usually nocturnal and have a lifespan between 1 and 3 years with 2 years being the average. It is the most commonly employed mammalian model organism which can be genetically modified.The house mouse has its origin in Asia and arrived in Britain in the 10th century, brought on via shipping.

Zebrafish
Danio rerio (id = 7955)
The tropcial freshwater zebrafish is an important vertebrate model organism in scientific research, It exhibits a typical generation time of three to four months. Zebrafish have restricted telomerase expression and human-like telomere length [http://denigma.de/url/3p].

Capuchin
Cebus capucinus (id = 9516)
Cebus capucinus is a small-sized (4-8 kg for adults) New World money that diverged from the lineage leading to humans about 35-40 million years ago. Among the primates, only humans, apes, and Cebus Capuchinus are known to live over 50 years [10462163]. The convergence of Cebus and humans in extreme longevity, as well as in other traits such as a large brain, makes Cebus and ideal organism to identify mechanisms and genes that contribute to these convergent traits.Cebus can live up to 54 years and is, after humans and apes, the best example of a long-lived primate lineage [17595413], and a clear outlier in terms of longevity with a much longer lifepsan than expected for its body size. In addition to extreme longeivty, a convergence of Cebus and Homo in other traits, such as a relatively large brain, has been observed [17595413].

Bowhead whale
Balaena mysticetus (id = 27602)
Bowhead whales get their name from the heads. The bowhead whale has a massive bow-shaped skull that is over 16.5 feet (5 m) long and about 30-40% of their total body length. This large skull allows that bowhead whale to break through thick ice with its head. The bowhead whale also has a 17-19 inch (43-50 cm) thick blubber layer, thicker than any other whale's blubber.Bowheads seem to be recovering from the harvest of Yankee commercial whaling from 1848 to 1919, which wiped out all but 1,000 or so animals. Because the creatures can live longer than 200 years (a fact discovered when an old stone harpoon pint in a whale) some of the bowheads alive today may have themselves dodged and barbed steel points on the Yankee whalers. thirty four years ago, Scientist counted 1,200 whales, while today there are about 14,000 of the mammals out there.

Marmoset
Callithrix jacchus (id = 38020)
Marmosets are New World monkeys. Most marmosets are tiny and just about 20 cm long. There is an ongoing project on age-related data in the Marmoset with preliminary results [21031036]. If the exact same measurements that are done in the marmoset project would also been done in humans, then it would be possible to start projections and learn a lot from this model.

Bony fish
Nothobranchius furzeri (id = 105023)
Turquoise killfish is a annual fish inhabiting ephemeral polls in semi-arid areas with scarce eratic precipitations. They adapted to the routine drying of their environments via evolving desiccation-resistant eggs that can remain dormant for one or more years by entering a kind of diapause. Because of the very short duration of the rains session, the natural lifespan of this species is limited to a few months and their captive lifespan is similar short, rendering them to excellent model system for aging research.Turquoise killfish is a annual fish inhabiting ephemeral polls in semi-arid areas with scarce eratic precipitations.
