The blue whale (Balaenoptera musculus) is the largest animal on Earth, and it is also the fattest. An adult blue whale can weigh up to 200 tons, and its body is composed of about 35% fat. This blubber layer helps the whale to stay warm in the cold ocean waters, and it also provides a reserve of energy that the whale can use when food is scarce.
The blue whale's blubber is also an important source of nutrients for the whale's calves. When a calf is born, it weighs about 2,000 pounds. Over the next few months, the calf will nurse on its mother's milk, which is rich in fat and protein. The calf will gain weight rapidly, and by the time it is weaned, it will weigh about 10,000 pounds.
The blue whale is an endangered species, and there are only an estimated 2,000 to 3,000 blue whales left in the world. One of the biggest threats to blue whales is commercial whaling. In the 19th and 20th centuries, blue whales were hunted for their blubber, which was used to make oil. Today, blue whales are protected by international law, but they still face threats from ship strikes, pollution, and climate change.
