Scientific classification
Species:B. mysticetus

Bowhead Whales belong to the Balaenidae family and are scientifically known as Balaena mysticetus. They are a species of baleen whale and are renowned for their massive size and unique features.

Quick Facts

Bowhead Whales can reach lengths of up to 60 feet (18 meters) or more.
They are among the longest-lived mammals, with some individuals surpassing 200 years.
These whales are characterized by their massive, bow-shaped heads and robust bodies.
Bowhead Whales are known for their ability to break through ice using their strong heads.


Bowhead Whales are easily recognizable by their prominent bow-shaped heads, which are enormous and make up around one-third of their total body length. Their skin is dark, often black, and can be covered with barnacles and other sea organisms. Unlike some other whale species, they lack a dorsal fin.

Distribution and Habitat

Bowhead Whales primarily inhabit the Arctic and subarctic regions, favoring the icy waters near the poles. They are highly adapted to life in frigid environments and are often seen in areas with sea ice. These whales undertake extensive migrations, following the seasonal shifts in their prey.

Biology of the Bowhead Whale

The biology of Bowhead Whales is a marvel of adaptation to extreme conditions. They possess a thick layer of blubber that helps them maintain body heat in freezing waters. Their baleen plates, which they use to filter their food, can grow up to 14 feet long.


Bowhead Whales are known for their slow and deliberate movements. They are generally solitary creatures but can be seen in small groups or pods. These whales are known for their powerful, resonant songs, which are thought to play a role in communication during the breeding season.


Bowhead Whales are primarily filter feeders, primarily consuming tiny organisms like krill, copepods, and other zooplankton. Their baleen plates efficiently filter these small creatures from the water.

Bowhead whale Life Span

Bowhead Whales are remarkable for their longevity. Some individuals have been estimated to live for more than two centuries, making them some of the oldest known mammals on Earth.

Bowhead whale Reproduction

These whales have a slow reproductive rate, with females giving birth to a single calf after a gestation period of over a year. Calves are nurtured by their mothers and have a dependency period of around one year before they become more independent.
