Abstract
We fit ongoing 40+-year mark-recapture databases from the thriving southern right whale (SRW), <i>Eubalaena australis</i>, and highly endangered North Atlantic right whale (NARW), <i>Eubalaena glacialis</i>, to candidate survival models to estimate their life spans. Median life span for SRW was 73.4 years, with 10% of individuals surviving past 131.8 years. NARW life spans were likely anthropogenically shortened, with a median life span of just 22.3 years, and 10% of individuals living past 47.2 years. In the context of extreme longevity recently documented in other whale species, we suggest that all balaenid and perhaps most great whales have an unrecognized potential for great longevity that has been masked by the demographic disruptions of industrial whaling. This unrecognized longevity has profound implication for basic biology and conservation of whales.
