Beluga whale reproduction
Beluga whale females will produce no more often than every 2-3 years, and usually only produce one young per birth. This makes the Beluga whales vulnerable to over-hunting. After a gestation period of around 15 months, young Beluga whales already weighs around 70 kilograms of birth in the spring. This will not be weaned until it has reached the age of 1.5 to 2 years. The estimated longevity Beluga whales are around 35-40 years old.

The Beluga whale females will usually become sexually mature at the age of five years, while males do not become sexually mature until they are at least eight years old. We still know little about the actual process of mating. Marriage is known to take place during the winter or early spring. Beluga whales can marry in their winter habitat or during spring migration. But there are a lot of reports about the mating lasted for another season, so that he may be capable of Beluga whales delayed implantation.
