The blue whale (Balaenoptera musculus) is a marine mammal belonging to the suborder Mysticeti of cetaceans. With up to 30 m in length and more than 180 t in weight, they are one of the largest animals that ever existed.
Long and slender, the body of the blue whales shows its dorsum in different blue-gray tones, while its belly is generally lighter. There are at least three distinct subspecies: B. m. musculus, whose habitat is restricted to the north of the Atlantic and Pacific Oceans, B. m. intermedia, of the Antarctic ocean and B. m. brevicauda (also known as pygmy blue whale), found in the Indian Ocean and South Pacific Ocean. B. m. indica, of the Indian Ocean, may be another subspecies. As is the case with other species belonging to the suborder Mysticeti, the blue whale diet consists almost exclusively of small crustaceans known as krill, which filter from seawater using horny blades in their mouth. However, they can also feed on small fish and squid.
Blue whales were, until the beginning of the 20th century, abundant in almost all oceans. Hunt for more than a century, they were brought to the brink of extinction by whalers until they became the object of protection mechanisms adopted by the international community in 1996. A 2002 report estimated that there are five to twelve thousand blue whales worldwide , distributed in at least five clusters. However, more recent research on the pygmy subspecies suggests that the current population is larger. Before being hunted, the largest group was in Antarctica, with approximately 239,000 individuals. The very small remaining clusters, with about 2000 individuals each, are located northwest of the Pacific, Antarctic, and Indian Oceans. Two other groups of blue whales are found north of the Atlantic Ocean, and there are at least two others in the Southern Hemisphere.
The dorsal fin of the blue whales is small, visible only for a short period of time, while diving. Through their spiracle, they can produce jets of water up to 9 m in height. The volume of your lungs can reach 5 000 ℓ. They are also the world's noisiest animals, and can emit sounds that reach 188 dB - stronger than the sound of a jet plane - and can be heard more than 800 km away. https://en.wikipedia.org/wiki/Baleia-...
