Nothobranchius furzeri

Nothobranchius furzeri, the turquoise killifish, is a species of killifish from the family Nothobranchiidae native to Africa where it is only known from Zimbabwe and Mozambique. This annual killifish inhabits ephemeral pools in semi-arid areas with scarce and erratic precipitations and have adapted to the routine drying of their environment by evolving desiccation-resistant eggs that can remain dormant in the dry mud for one and maybe more years by entering into diapause. Due to very short duration of the rain season, the natural lifespan of these animals is limited to a few months and their captive lifespan is likewise short, making them an attractive model system for ageing and disease research. Among vertebrates, the species has the fastest known sexual maturity – only 14 days after hatching and shortest lifespan – ranging 3 to 12 months depending on the environment. This species can reach a total length of 6.5 cm (2.6 in). [From Wikipedia, the free encyclopedia]
