Lifespan/Longevity
In an 18-year study of energy storage in Antarctic minke whales, Konishi et al. (2008) aged a total of 4,268 mature whales (mature males and pregnant females). They used measurement of the earplug, a layered keratinized and fatty structure inside the external auditory canal, to determine age. The oldest whale aged in their study was 73 years old according to this technique.
Range lifespan
Status: wild: 73 (high) years.
