Once female blue whales reach sexual maturity around 5 to 15 years old, they can give birth every two to three years. Blue whale pregnancies last about one year with calves typically born in December to February in low latitudes.10,000-25,000
Before whaling, there may have been as many as 250,000 blue whales, but today, it is one of the world's rarest species, with a population of just 10,000-25,000.For example, in the North Atlantic and North Pacific, blue whales can grow up to about 90 feet and are over 100,000 pounds, but in the Antarctic, they can reach up to about 110 feet and weigh more than 330,000 pounds. Like many other baleen whales, female blue whales are generally larger than males.
How old do blue whales get : Scientists have discovered that by counting the layers of a deceased whale's waxlike earplugs, they can get a close estimate of the animal's age. The oldest blue whale found using this method was determined to be around 110 years old. Average lifespan is estimated at around 80 to 90 years.
Do blue whales mate for life
Reproduction. The blue whale reaches sexual maturity at about six to ten years old. After that, it mates every two years — though not necessarily with the same partner. Pairs may stick with the same partner for multiple years but are not known to pair for life.
What happens when a blue whale dies : When whales die and sink, the whale carcasses, or whale falls, provide a sudden, concentrated food source and a bonanza for organisms in the deep sea. Different stages in the decomposition of a whale carcass support a succession of marine biological communities. Scavengers consume the soft tissue in a matter of months.
There are an estimated total of 1,000–3,000 whales in the North Atlantic, 3,000–5,000 in the North Pacific, and 5,000–8,000 in the Antarctic. Blue Whales
Today, an estimated 10,000 to 25,000 of these majestic animals swim throughout the seas. They have an endangered designation from the International Union for Conservation of Nature.

10,000 to 25,000
Blue whales are found in every ocean, but population numbers are far lower than before the whaling boom. Today, an estimated 10,000 to 25,000 of these majestic animals swim throughout the seas. They have an endangered designation from the International Union for Conservation of Nature.To date, the only known natural predator of the blue whale is the orca.The Blue Whale has been reported to live to over 100 years (average more 70 than years). Blue whales are also the largest whales. Bowhead whales
Bowhead whales are considered to be the longest-living mammals, living for over 200 years.
Do whales love humans : Historical research paints a much different picture, but today, modern research shows us that whales are and always have been typically a friendly species. Today when whales are spotted, their relationships with humans are now amicable, social, and inquisitive.
Do whales love their babies : Cetaceans are champion mothers, dedicating months or even years to raise their young. Making her calf her top priority requires an enormous amount of her time and energy. However, these maternal efforts make it possible to ensure the calf's survival and, ultimately, to continue the lineage.
Do whales mourn their dead
Humpback whales, a member of the baleen whale family, are heard weeping and mourning for a companion that is beached, and in a heartbreaking experience, a killer whale was observed as it pushed and nuzzled its dead calf for up to six hours. Eventually the ocean giant will begin to sink, falling kilometre after kilometre, until finally coming to rest on the seabed. This is when the carcass becomes known as a whale fall. Whale falls can nourish an entire ecosystem of deep-sea creatures, from large scavengers to microscopic bacteria.The vaquita
The vaquita is the most endangered cetacean in the world. With as few as around 10 left, the species will become extinct without a fully enforced gillnet ban throughout their entire habitat. WWF is urgently working to ensure they can live and thrive in their natural habitat.
Are blue whales friendly : před 6 dny
Blue whales are often referred to as the “gentle giants” of the ocean, and for good reason. Despite their massive size, they are known for their calm and docile behavior. They are curious creatures and have been observed approaching boats and interacting with humans in a friendly manner.
