The taxon was described by Linnaeus in 1758 and has existed since the Late Pleistocene, with a start time of about 200 thousand years ago.

Its primary food source is zooplankton. The species has a gestation period of 11 months and a longest observed lifespan of 211 years. According to the IUCN Red List from 2018, its conservation status is Least Concern, while iNaturalist lists it as vulnerable. It is included in Appendix I of CITES.

Maximum longevity: 211 years (wild) Observations: These animals exhibit slow growth and high survival. Growth may be faster in females than in males, and it slows down markedly at around 40-50 years of age. Sexual maturity is probably reached at age 20-25. Using an indirect method for age estimation based on aspartic acid racemization, the bowhead whale has been recorded as the longest-lived mammal thanks to one male estimated to be 211 years-old. The same study found three other male specimens estimated to be over 100 years of age. Very few obvious signs of pathology were found in old bowheads. The 211 year-old specimen was reported to appear old with though meat and blubber. One of the centenarian males exhibited a spondylitic lesion on the vertebra. Reproductive senescence has not been reported, though detailed studies are lacking (George et al. 1999).

الحوت المقوس الرأس (باللاتينية: Balaena mysticetus) والذي يعرف أيضاً باسم الحوت غرينلاند الصائب وحوت الأرقتيق هو حيوان ثديي مائي، ينتمي إلى الحيتانيات (حوت)، ويعيش في المحيط المتجمد الشمالي قرب كتل الثلج العائمة، خاصة في بحر جرينلاند، مضيق دافيس، وبحار سيبيريا. يبلغ طول الحوت المقوس الرأس حوالي 20 متراً ووزنه 80 طناً، ويصل طول زعنفته الذيلية إلى 7 أمتار تقريباً. لونه أسود ويتميز بوجود بقعة بيضاء تحت فمه. اعتبر هذا الحوت من أكثر الحيتان التي كانت تصطاد تجارياً، مما أدى إلى انخفاض عددها بشكل كبير. و هو حوت نادر لم يبق منه الا 250 فردا في النصف الشمالي و3000 في النصف الجنوبي، ولا يظهر غالبا في جماعات ربما لتقلص عدده. يصل طوله إلى 16 مترا ووزنه إلى 60 طنا.
