Lifespan, longevity, and ageing
Maximum longevity: 54 years (wild) Observations: Not much is known about the life history of these animals, the world's largest fish. One study estimated annual survival at 0.825. Age at maturity probably occurs at 13 to 25 years. Maximum longevity is unknown with estimates ranging from 54 years to over 100 years (Bradshaw et al. 2007).
