The world's largest animal, the blue whale, lives an average of 80 years. Natural enemies are killer whales and humans. Blue whales, like other toothless whales, prey on zooplankton (especially krill). Although their name is blue whale, their colors are blue-gray mix. It is also the second loudest animal in the world, after the sperm whale.

Physical characteristics of the blue whale blue whale The blue whale's head, which is the largest living animal, is flat when viewed from the side and U-shaped from the top. The sky whale's breathing holes are twin and quite large. The spray formed while exhaling through these holes can reach a height of 6 to 12 meters. About 60 to 90 grooves on the neck extend parallel to the body, and thanks to these grooves extending to the abdomen, the throat of the blue whale is incredibly wide and facilitates its feeding. The gigantic creature, which appears flat blue or gray when viewed from the water, has a long body tapering from its head to its tail. The blue whale, the largest animal in the world, has a small dorsal fin and is often seen when diving. Pectoral fins are about 3-4 meters long. The tail fin is solid gray in color. The rear edge of the tail fin, which is broad and triangular, is smooth, and the two halves of this edge coming from the tail wings converge in a prominent recess in the middle. The blue whale is known as the largest animal in the world, weighing more than 140 tons. Argentinosaurus is the largest creature known to have lived in the age of dinosaurs, and it is estimated that even the weight of this creature can reach up to 90 tons. Blue whales, which have a huge size, are very difficult to measure. Celestial whales killed by hunters were not measured as a whole, but in movable parts. Given the weight of blood and various fluids lost during the lysis process, the results obtained about the weight are incomplete. The largest blue whales on record are 45 meters long and weigh 300 to 450 tons. Researchers at the American National Marine Mammal Laboratory (UDML) estimate that a 30-meter blue whale would weigh more than 250 tons. The most accurate weight the UDML has been able to measure to date is 177 tons and the length is 29.9 meters.

How do blue whales feed? blue whale The blue whale, the largest animal in the world, mostly feeds on small crustaceans called krill. However, it rarely hunts small fish. Celestial whales spread to the regions with the most food during the feeding season. During this period, they wander single or double and can be seen in open waters or near the shore. Blue whales that hunt large herds of krill, feed at depths of more than 100 meters during the day and close to the surface at night. They open their mouths to feed and take in nutrient-filled seawater. Blue whales dive for hunting and the average dive time for feeding is 10 minutes. However, the longest recorded dive time is 36 minutes. A sky whale in the feeding season consumes 2 to 4 tons of krill per day.
