A descriptive name given on account of the many ways the head suggest “bows;” the profile of the head resembles the “bow of a boat,” the upper jaw is arched like an archer’s bow, and the baleen arches like a taught bow.
The baleen in the bowhead is the longest of the baleen whales with plates reaching 4 meters (15 feet). The bowhead has over 300 plates of baleen on each side of their head, so while they were hunted for oil, the baleen was also sought for many products until plastic became the rage – another case where ironically the petroleum industry had a hand in saving the whales.
This cousin of the Right Whale resides exclusively in the Arctic. They follow the advance and retreat of the lead ice and can break through 12” of ice, and are often accompanied by belugas.
The lifespan of most whales have been framed in the context of human longevity, despite the lack of any substantiating evidence. This was until a Bowhead was recently taken by subsistence hunters who found an ivory spear point lodged in its blubber of a type that had not been used for 200 years.
