exact age was known for animals first catalogued as calves. Animals without a known year of birth were assigned a minimum age by assuming that the whale was at least one year old the first time that it was sighted. Female humpback whales in the Gulf of Maine have been shown to reach sexual maturity at an average age of five years (Clapham, 1992), a

Balaenoptera is a diverse genus and comprises all but one of the extant species in its family—the other species is the humpback whale (Megaptera novaeangliae). This genus is known in the fossil records from the Neogene to the Quaternary (age range: from 13.65 million years ago to the present).
