[110] [111] They reach sexual maturity when 13 to 14 m (43 to 46 ft) long. Baleen whales are K-strategists, meaning they raise one calf at a time, have a long life-expectancy, and a low infant mortality rate. [112] Some 19th century harpoons found in harvested bowheads indicate this species can live more than 100 years. [113]
