The scientific name, Megaptera, means "large winged" 

 Humpback whales can live up to 70 years of age, the average being approximately 50. The females are larger than the males, and can measure from 45 to 50 feet (13.7-15.2m). A male measures from 40 to 48 feet (12.2 to 14.6m) They can weigh from 25 to 45 tons ( 22,680 to 36,287 kg). They reach sexual maturity at 6-8 years of age. A female may give birth once every 2 to 3 years, the gestation period being 12 months. A calf will nurse from 8-11 months of age and, once weaned, they are 24 to 27 feet in length. They will leave this mother-calf bond generally following the next spring migration to feeding grounds.
