Contradictory Data

Abstract The longevity-homeoviscous adaptation (LHA) theory of aging states that lipid composition of cell membranes is linked to metabolic rate and lifespan, which has been widely shown in mammals and birds but not sufficiently in fish. In this study, two species of the genus Amphiprion (A. percula and A. clarkii, with estimated maximum lifespan potentials [MLSP] of 30 and 9-16 years, respectively) and the damselfish Chromis viridis (estimated MLSP of 1-2 years) were chosen to test the LHA theory of aging in a potential model of exceptional longevity. Brain, livers and samples of skeletal muscle were collected for lipid analyses and integral part in the computation of membrane peroxidation indexes (PIn) from phospholipid (PL) fractions and PL fatty acid composition. When only the two anemonefish were compared, results pointed to the existence of a negative correlation between membrane PIn value and maximum life expectancy, well in line with the predictions from the LHA theory of aging. Nevertheless, contradictory data were obtained when the two clownfish were compared to the shorter-lived C. viridis. This results along with those obtained in previous studies on fish denote that the magnitude (and sometimes the direction) of the differences observed in membrane lipid composition and peroxidation index with MLSP cannot explain alone the diversity in longevity found among fishes.
