A beluga whale is typically pregnant for 14 to 15 months.
Beluga whales undergo a significant gestation period before giving birth to their calves. Based on research and observations, the average pregnancy duration for a female beluga whale is quite lengthy. According to information from May 16, 2021, beluga whales have a gestation period of 14-15 months. This extended period means the mother whale experiences substantial growth and physiological changes to support the developing calf.
Understanding Beluga Whale Gestation
The gestation period is the time during which a mammal carries a developing embryo or fetus in its uterus. For beluga whales, this timeframe is crucial for the calf to develop sufficiently before being born into the cold Arctic and sub-Arctic waters they inhabit. The 14-15 month duration is relatively long compared to many other mammals, highlighting the significant investment a mother beluga makes in her offspring.
Here's a quick look at the gestation:

Beluga Whale Reproduction Insights
Understanding the gestation period is part of a broader picture of beluga whale reproduction. These social whales usually reach sexual maturity between 4 to 7 years for females and 6 to 9 years for males.
Key points about beluga reproduction include:
- Birthing Season: Calving typically occurs during the warmer summer months after the long gestation period, often in shallow waters or estuaries.
- Calf Appearance: Newborn calves are usually grey or brownish and gradually turn white as they mature, a process that can take several years.
- Parental Care: Mothers provide intensive care, nursing their calves for up to two years.
- Reproductive Rate: Beluga whales generally give birth to a single calf every two to three years.
The extensive gestation period, followed by a long period of nursing and maternal care, underscores the slow reproductive rate of beluga whales, which is an important factor in their population dynamics and conservation status.
