Blue whales, also known as the fish he is a whale species belonging to the suborder Mysticeti (baleen whales). [9] at 30 metres (98 ft) [10] and weighing 180 tonnes (200 short ton) [11] or even further, it is the largest surviving animals and heaviest ever existed. [12]The body is long and slender, the blue whale can be bluish-grey color in the light than in the lower back and abdomen. [13] at least three subspecies of the blue whale: b. m. musculus lives in the waters of the North Atlantic and North Pacific, b. m. intermedia lives in South Ocean and b. m. brevicauda (Pygmy blue whales) live in the Indian Ocean and the South Pacific. Like other whales, their food is mainly plankton and small crustaceans. [14]Before the 20th century, blue whales exist with large number of fish in most of the oceans of the world. But more than 100 years, they hunted to near extinction until they were protected by international law in 1966. According to a report in 2002, there were approximately 5000-12000 individuals living throughout the world, [15] including at least 5 groups. Before hunted, spurring the biggest blue whale populations in the Antarctic waters has about 239,000 individuals (from 202,000 to 311.000). [16] other smaller populations (approximately 2000 individuals) are concentrated in the North-Eastern Pacific waters, Antarctica. Have 2 other populations in the North Atlantic and at least two more populations in the southern hemisphere. By 2014, the number of blue whales in California has recovered to levels almost before the hunting period. [17]The largest blue whale scientists here have children đolà 177 tons. [15]Within 7 months after birth, the baby blue whales drink about 400 litres (110 Us gal) of milk per day, so the volume it increased very quickly in about 90 kilograms (200 lb) per 24 hours. Even at birth it already weighs 2700 kilograms (6000 lb) — equal to the volume of a hippopotamus (hippopotamus). [9] the blue whale has a relatively small brain (6.92 kilogram (15.26 lb)), only by about 0.007% of its body mass.The largest blue whale scientists here have children đolà 177 tons. [15]Blue whales feed almost exclusively moi Unicorn, with a small amount of animal's flippers. [25] The species of zooplankton to whales eat depending on the sea that it sốngMột the adult blue whale can consume up to 40 million by the moi on a Unicorn. [26] they always feed in the regions densely moi Unicorn at most, occasionally consume up to 3600 kg (7900 lb) moi Australia within a day. [25] The daily energy requirement of an adult blue whale is in the region of 1.5 million kilocalories. [40] Their feeding habits are seasonal. Blue whales gorge on krill in the rich waters of the Antarctic before migrating to their breeding grounds in the warmer, less-rich waters nearer the equator. The blue whale can take in up to 90 times as much energy as it expends less, allowing it to build up considerable energy reserves. [41] [42] [43]Because krill move, blue whales typically feed at depths of more than 100 mét (330 ft) during the day and only surface-feed at night. Dive times are typically 10 minutes when feeding, though dives of up to 21 minutes are possible. The whale feeds by lunging forward at groups of krill, taking the animals and a large quantity of water into its mouth. The water is then squeezed out through the baleen plates by pressure from the ventral pouch and tongue. Once the mouth is clear of water, the remaining krill, unable to pass through the plates, are swallowed. The blue whale also incidentally consumes small fish, crustaceans and squid caught up with krilVì kích thước khổng lồ, sức mạnh và tốc độ của mình, cá voi xanh hầu như không có thiên địch trong tự nhiên.Cá voi xanh có thể bị thương, thậm chí tử vong, do va chạm với tàu bè hay bị vướng vào lưới đánh cá.[Cá voi xanh là một loài nguy cấp trong Sách đỏ IUCN kể từ khi sách này được công bố

Blue whales, also known as the whale is a whale belongs Mysticeti division (baleen whales). [9] Length 30 meters (98 ft) [10] and weighs 180 tons (200 short ton) [ 11] or even more, it is the largest animal remains and heaviest ever existed. [12] The body long and slender blue whale, may have bluish-gray on the back and light than on the abdomen. [13] There are at least three blue whale subspecies: B. m. musculus live in waters north Atlantic and north Pacific, B. m. intermedia live in the Southern Ocean and B. m. brevicauda (pygmy blue whale) live in the Indian Ocean and the South Pacific. Like other whales, their food mostly plankton and small crustaceans. [14] Before the 20th century, blue whales exist with large number of individuals in most oceans world. But more than 100 years, we hunted to near extinction until protected by the international law in 1966. According to a report in 2002, there were approximately 5000-12000 individuals living around world, [15] including at least 5 groups. Before being hunted, the blue whale population the largest in Antarctica waters around 239,000 individuals (from 202,000 to 311,000). [16] The smaller population (approximately 2,000 individuals) are concentrated in the east coast north Pacific, Antarctica. There are two different populations in the North Atlantic and at least two more populations in the Southern Hemisphere. In 2014, the number of blue whales in California have recovered to near pre hunting period. [17] The largest blue whale scientists here Dola children weighing 177 tons. [15 ] In the first 7 months after birth, baby blue whale drinks approximately 400 liters (110 US gal) of milk each day, so the volume it increased rapidly to about 90 kilograms (200 lb) every 24 hours. Even at birth weighs 2,700 kilograms it (6,000 lb) weight -by a hippopotamus (hippopotamus) mature. [9] Blue whales have relatively small brains (6.92 kilograms (15.26 lb )), only about 0.007% of its body weight. The largest blue whale scientists here Dola children weighing 177 tons. [15] Blue whales feed almost every time, with a small amount of animal flippers. [25] The species of whales eat plankton, depending on the seas but it songMot adult blue whale can consume up to 40 million children each time a day. [26 ] We always foraging in areas with highest density of each time, occasionally consume 3,600 kilograms (7,900 lb) each time in just over a day. [25] The daily energy requirement of an adult blue whale is in the region of 1.5 million kilocalories. [40] Their Habits are seasonal feeding.
