Blue Whale Beluga Killer Whale Details

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.

1.Blue whales are marine mammals that belong to the family of baleen whales. There are four subspecies. At 33 meters long and weighing 181 tons, the blue whale is considered the largest known animal on Earth. The blue whale is thin and long, with a blue-gray back, but sometimes it looks light in the water.

2.Like other baleen whales, blue whales feed primarily on small crustaceans (such as krill) and small fish, sometimes including squid. Usually, blue whales need to feed on the seafloor above 100 meters during the day and can only feed on the surface at night.

Blue whales begin mating in late autumn and continue until the end of winter. Females usually give birth every 2-3 years. After 10-12 months of pregnancy, they usually give birth to cubs in early winter.

All four oceans are distributed.

3.The blue whale is not only the largest cetacean, but also the largest living animal. They are by far the largest mammals.

It is generally 22-33 meters long and weighs 150,000-180,000 kilograms, which means that its weight is equivalent to the weight of more than 25 African elephants, or the total weight of 2,000-3,000 people. Fortunately, due to the buoyancy of the ocean, it does not need to be as rigid as land animals to support its own weight. In addition, its huge body helps to maintain a constant body temperature.

Southern Blue Whale (Intermedia Burmeister, 1871) Southern Blue Whale is found in the Southern Hemisphere; The female of the southern blue whale is 23 24 m long, the male is 22 m long, and the body length of the mature body is 26 27 m and 24 25 m, respectively.

Northern Blue Whale (Musculus Linnaeus, 1958) The Northern Blue Whale is found in the North Atlantic and North Pacific Oceans. The female of the northern blue whale is 21 23 m long, and the male is 20 21 m long, and the body matures at 25 and 24 m long, respectively.

Brevicaukta Ichihara, 1966 Brevicaukta Ichihara, a small blue whale found in the subantarctic waters of the Indian Ocean and the Southeast Atlantic. The female is 19 m long, the male is slightly less than 19 m long, and the male is 22 and 21 m long, respectively.

Size comparison: The blue whale is the largest animal that has ever lived on Earth. The largest known creature from the age of the dinosaurs is the Mesozoic Argentinosaurus, which was estimated to weigh 90 tons (100 short tons). How much the largest blue whale weighs is uncertain.

Most of the data is taken from blue whales killed in Antarctic waters in the first half of the 20th century, and the data were measured by whalers who were not proficient in standard animal measurement methods. The longest whale recorded were two females, m (110 ft 3 in) and m (109 ft 3 in). But the reliability of these measurements is controversial.

Scientists at the National Marine Mammal Laboratory (NMML) measured the longest whale to be meters (98 feet) long, about as long as a Boeing 737 or three double-decker buses.

The killer whale is a large toothed whale, with a length of 8 10 meters, a weight of about 9 tons, a black back, a grayish-white belly, a pointed dorsal fin, the dorsal fin is curved up to 1 meter, the mouth is slender, the teeth are sharp, the temperament is fierce, carnivore, good at attacking prey, is the natural enemy of penguins, seals and other animals. Sometimes they also attack other cetaceans, even great white sharks, which can be called the overlords of the sea.
