What do Bowhead Whales eat?
Bowhead Whales continuously feed by swimming with their mouths open, sifting water through their baleen plates to strain out plankton. They consume up to 2 tons of plankton daily. Their dives can last up to 40 minutes but are usually not very deep.
Are Bowhead Whales social?
Bowheads can be solitary or form small pods of up to 6 members, sometimes as large as 14. They are vocal, using various songs for communication. In June 2015, an exceptional sighting of 80-100 Bowhead Whales was recorded on the North Atlantic Odyssey.
How fast can Bowhead Whales swim?
While feeding, they cruise at 2-3 km per hour but can reach speeds of nearly 20 km per hour in short bursts.
What are Bowhead Whale mating rituals like?
Bowheads mature sexually at 10-15 years. Females give birth every 3-4 years, with a 13-month pregnancy. Calves are born tail-first, weighing about 1,000 kg and measuring 4.5 meters. They double their length in the first year and are weaned after a year.
How long do Bowhead Whales live?
Bowheads were originally thought to live around 65 years, but findings of old harpoon heads suggest they can live up to 200 years.
How many Bowhead Whales are there today?
Estimates place their population between 10,000 to 25,000.
Do Bowhead Whales have any predators?
Killer Whales are their only natural predators, but it takes a pod of Killer Whales to pose a significant threat.
