Observations

The turquoise killifish is an extremely short-lived animal that shows an accelerated ageing process. Compared with similar species, these animals also mature earlier and grow quicker [0663]. They are the shortest-lived vertebrate species bred in the lab [1197]. Large differences in ageing phenotypes have been observed between strains with maximum lifespan in a laboratory strain reportedly of 32 weeks [0889]. However, wild-derived populations can live over one year in the lab [1120]. Differences in lifespan between strains have been genetically linked to sex [1227]. The sex chromosomes of turquoise killifish display features of early mammalian XY evolution [1228].

Ageing turquoise killifish show reduced learning performances, gliosis and reduced adult neurogenesis. One study demonstrated that as these animals age neurogenesis and extracellular matrix genes rapidly decay in the brain and synaptic and axonal genes progressively decay [1198]. Genes related to ageing are clustered in specific regions of the genome [1228]. Telomerase deficient turquoise killifish display the fastest onset of telomere related pathologies among vertebrates [1197].
