Life Span Assessment in the African Turquoise Killifish .

The African turquoise killifish () is the shortest-lived vertebrate bred in captivity, with a median life span of 4-6 mo. Within its short life span, the killifish recapitulates critical aspects of human aging, including neurodegeneration and increased frailty. Developing standardized protocols for life span assessment in killifish is critical for identifying environmental and genetic factors that impact vertebrate life span.
