Lifespan/Longevity
Berardius bairdii can live to be 84 years old in males and 54 years old in females. Age in odontocetes (toothed whales) is determined by counting rings in the teeth, similar to the annual rings in a tree. Nothing is known about the lifespan of B. arnuxii, but it is assumed to be similar to that of B. bairdii.
