Information about the Great Blue Whale see question supplement .

1. The blue whale is a marine mammal and belongs to the suborder baleen whale. There are four subspecies in the Changqing section. The blue whale is believed to be the largest known animal on Earth to survive in terms of volume, reaching up to 33 meters long and weighing 181 tons.

The blue whale has a slender body and a blue-gray back, although it can sometimes be lighter in the water.

2. Like other baleen whales, blue whales feed mainly on small crustaceans (e.g., krill) and small fish, sometimes including squid. Blue whales usually feed at depths of more than 100 meters during the day and come to the surface at night. Blue whales begin mating in late autumn and continue until late winter, with females usually giving birth every 2-3 years and calves at the beginning of winter after a gestation period of 10-12 months.

It is distributed in all four oceans.

3. The blue whale is not only the largest cetacean, but also the largest living animal, the largest mammal to date. It is generally 22-33 meters long and weighs 150,000-180,000 kilograms, which means that it weighs as much as more than 25 African elephants, or 2,000-3,000 people combined. Fortunately, due to the buoyancy of the ocean, it does not need to work as hard to support its weight as a land animal, and its large body helps to maintain a constant body temperature.

The blue whale is currently the largest living creature on Earth, and there is no creature that is 100 million times larger than the blue whale. For the blue whale, the largest animal on our planet, the low-frequency sound it emits in the sea can only stretch for a maximum of 80 kilometers, which is a whole double the difference from the monster found this time. Dinosaurs, such as some sauropods, were huge, up to 30 to 60 meters long and weighing up to 50 150 tons.

How does the blue whale live?

One is that whales do not drink seawater, instead, they extract water from their food by metabolizing fats. While their specific range varies from species to species, whales live in oceans around the world. Because whales have a lot of fat in their bodies, they can easily float in the water.

The second is that, like dolphins, whales are believed to be descendants of land animals that have lived on land for millions of years and returned to the water about 50 million years ago. About 50 million years ago, whales walked on land and were about the size of wolves.

The third is that whales have to surface frequently to breathe, so only half of the continent is sleeping. Whale earwax shows the age of the whale, similar to the way tree rings reveal the age of a tree.

Fourth, sperm whales can dive up to two miles deep in the water, and their bodies have unique physiological adaptations that allow them to survive the intense cold and oppressive stress of diving. The blue whale is the largest whale in the world and is also considered the largest animal in the world. Adult blue whales can reach up to 108 feet in length and weigh up to 200 tons.

Fifth, because each type of whale's tail has its own unique characteristics, it allows whale watchers to identify different species from a distance. The blue whale calls louder than a jet engine and can last up to 30 seconds, and the sperm whale is actually the loudest whale in the world.

Sixth, whales have no other natural predators other than humans. Humans have been hunting large mammals for thousands of years for their meat and other raw materials. Sperm whales sleep upright in the water, their noses poking out of the water.
