Blue whales Mating Habits

Blue whales are monogamous, mating during winter or early spring in warmer, tropical waters. Gestation lasts for almost a year, with the female giving birth to one calf when she returns to the region the next year. Having spent all summer feeding in the cold, rich waters of the Antarctic, the mothers eat almost nothing during the time they are providing their young with milk. 

Baby blue whales stay with their mother for at least a year and are weaned at about 8 months old. Blue whales can start reproducing between the age of 10-15 years old, producing a calf every 2 or 3 years.
