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.
