Median age at death is calculated from natural and clinical deaths only; maximum observed age includes animals with any type of death. Maximum ages are from the current dataset only; there are known older animals of some of these species at research institutes, such as a 29-year-old titi monkey male at CNPRC and two 19-year-old male marmosets at SNPRC but these did not meet this study’s filtering criteria (see methods).
