Researchers from Japan explore the effects of housing density during the juvenile stage on whole-life traits, including growth, fecundity, and lifespan, in African turquoise killifish.

Within the same species, individuals exhibiting faster growth tend to have shorter lifespans, even if their fast growth arises from early-life pharmacological interventions. However, in vertebrates, the impact of the early-life environment on the growth rate and lifespan has not been fully elucidated.
