The blue whale (Balaenoptera musculus) is a marine mammal and a baleen whale. Reaching a maximum confirmed length of 29.9 m (98 ft) and weighing up to 199 t (196 long tons; 219 short tons), it is the largest animal known ever to have existed.
The largest accurately measured blue whale was a 29.5-metre female that weighed 180 metric tons (nearly 200 short [U.S.] tons), but there are reports of 33-metre catches that may have reached 200 metric tons. The heart of one blue whale was recorded at nearly 700 kg (about 1,500 pounds).
The Blue Whale is the largest animal of our time and the largest animal that ever lived. But how large are they exactly? This animation will show you. ...more.
The average weight for blue whales is 200,000 to 300,000 pounds (90,000 to 136,000 kilograms), or about 100 to 150 tons. Some can weigh as much as 441,000 pounds (200,000 kilograms) or...
The blue whale is much larger than a human and can measure up to 33 meters (109 feet). That’s about four times the size of an African elephant, the largest land mammal. A blue whale is also larger than a humpback whales, sperm whales, or baleen whales. A female blue whale is about 21-27 meters (70-90 feet).
Blue whales are the largest animals ever known to have lived on Earth. These magnificent marine mammals rule the oceans at up to 100 feet long and upwards of 200 tons. Their tongues...
The largest blue whale ever found stretched 33 meters (108 feet) and was caught by whalers in the early 1900s. Usually, however, they can range between 24 and 30 meters (78-98 feet) in length, depending on where they live. Some of the largest reside in the Antarctic.
For example, in the North Atlantic and North Pacific, blue whales can grow up to about 90 feet and are over 100,000 pounds, but in the Antarctic, they can reach up to about 110 feet and weigh more than 330,000 pounds. Like many other baleen whales, female blue whales are generally larger than males.
The blue whale can grow to be 80 – 100 feet long (60 – 80 ft. on average) and weigh more than 150 tons when it is fully matured. Although blue whales can grow to be massive marine animals, they have slender, streamlined bodies that easily move through the ocean with very little water resistance.
The heart of an average-sized blue whale weighs 400 pounds (180 kg) and is the largest known in any animal. They cannot swallow big objects. Despite the gigantic size of its mouth, a blue whale cannot swallow an object wider than a beach ball due to its relatively narrow throat.
