Largest living animal blue whale .
Hi friends today we are going to discuss the largest living animal in te world Once the most important of the commercially hunted baleen whales, the blue whale was greatly reduced in numbers during the first half of the 20th century. In the 1930–31 season alone the worldwide kill of blue whales exceeded 29,000. The species has been protected from commercial whaling since the mid-1960s. Populations of blue whales appear to be recovering and are estimated worldwide at between 10,000 and 25,000 animals. However, the International Union for Conservation of Nature still lists the blue whale as an endangered speciesOnce the most important of the commercially hunted baleen whales, the blue whale was greatly reduced in numbers during the first half of the 20th century.

Populations of blue whales appear to be recovering and are estimated worldwide at between 10,000 and 25,000 animals. However, the International Union for Conservation of Nature still lists the blue whale as There are currently five subspecies of blue whale, recognized by the Society for Marine Mammalogy's Committee on Taxonomy: B. m. musculus in the North Atlantic and North Pacific, B. m. intermedia in the Southern Ocean, B. m. brevicauda (the pygmy blue whale) in the Indian Ocean and South Pacific Ocean, B. m. indica in the Northern Indian Ocean, and B. m. unnamed subsp. in the waters off Chile. The blue whale diet consists almost exclusively of euphausiids (krill).The blue whale was once abundant in nearly all the oceans on Earth until the end of the 19th century. It was hunted almost to the point of extinction by whaling until the International Whaling Commission banned all hunting of blue whales in 1967. The International Whaling Commission catch database estimates that 382,595 blue whales were caught between 1868 and 1978. The global blue whale population abundance is estimated to be 10,000-25,000 blue whales, roughly 3-11% of the population size estimated in 1911.There remain only much smaller concentrations in the Eastern North Pacific (1,647),Central North Pacific (63-133),North Atlantic (1,000-2,000),] Antarctic (2,280),New Zealand (718), Northern Indian Ocean (270), and Chile (570-760).so thanks for visiting
