They are sharks not whales that can reach upto 20 meters in lengths. Females are generally larger than males, and have an average length of If you want to see a more in-depth comparison of these two aquatic giants, click on the link below.
Most sauropod dinosaurs, the largest and heaviest species of dinosaurs cannot match the average range mass of blue whales, although the now extinct individuals such as the Dreadnoughtus and Paralititan are speculated to surpass the blue whale in length.
The specimens are also believed to have stretched a whooping 30 to 40 meters in length, which if true, means that they are one of the very few animals that can rival the lengths of blue whales. Or in other words, they may well be the largest animals to have ever stepped foot on earth. Now back to the gist, the standard football field measures 90 to meters in length. In short, the height of Burj Khalifa is the equivalent of 27 to 34 blue whales lined up end to end.
And as for the weight? Just forget about it. Why blue whales chose krills is because of the global increase in upwelling nutrient rich waters rising from the depths of the oceans which coincided with their evolution. This specialty gave rise to their enormous sizes in the following way. A blue whale calf or baby weighs 2, to 2, kilograms 5, to 6, pounds and stretches 23 feet 7 meters long at birth, on average. Putting things into different perspectives, a new born calf can weigh as much as one African forest elephant.
Then, the calf only increase in weight irregularly until it attains maturity at the age of 5 to 15 years. It may also gain weight after maturity but not substantially. Earlier, we discussed about the overall sizes of blue whales. Proportionately, very small. In comparison, humans have a 1. The animals with the largest known brains are the sperm whales. They have brains averaging 7. So big that you and of your friends could easily fit inside.
A blue whale can swallow more than 80, liters of water in single gulp, compare that to the measly 0. According to recent investigation in , the heart of the average blue whale weighs only a little over kilograms pounds and stretched 1. The scientists who took the measurement were able to do so from a Comparatively, the blue whales heart weighs about times as much as a humans heart at 10 ounces and less than half a percent of the entire body weight , 14 times as much as an elephants heart at 30 pounds and 5 percent of the entire body weight , or nearly as much as a bumper car.
At this size, the blue whale has the largest heart of any mammal on earth, and at least four average people can be squeezed inside. And one more thing, a diving blue whale has the slowest heart rate of any mammal, beating at a rate of four to eight cycles per minute.
And the impressive thing about this is that the sound can be heard over 4 kilometers away. The Aorta of blue whales, the main artery that pumps oxygenated blood throughout bodies, is only big enough to contain the head of the average human. The aorta typically measures over 9 inches across, or the size of a dinner plate. When they exhale, the speed can clock a mindboggling kilometers per hour, and they exhale nearly 90 percent of the total lung capacity.
In comparison with human lungs at 24 to 27 cm in length and 6 liters capacity, blue whale lungs are over 30 meters longer and wider. Blue whales eat krill , crustaceans that are similar to shrimp. During feeding season, blue whales must eat two to four tons of krill each day. They dive for minutes at a time to feed. They eat by expanding their throat plates, which sucks in water and krill. The blue whale has the loudest voice in the animal kingdom. Its voice can travel over hundreds or even thousands of miles.
This means blue whales who appear to be traveling alone may still be in contact with other whales. Blue whales are mammals. They give birth to calves that already weigh 3 tons and are 25 feet long. Because female blue whales must produce so much milk, they store extra energy and are larger than males.
The ocean can get pretty darn cold, especially the deep ocean. Also, having a big body can mean that an animal is able to survive longer stretches in between meals. So if a whale needs to travel great distances to find the next school of krill, its big body, with large fat reserves, can make the trip. Lastly, some scientists also theorize that modern whales evolved to be so large as a means to deal with large predators.
An adult blue whale is so gigantic that almost nothing can try to kill it and eat it. The only thing in the ocean that has any hope is a large pod of orcas Orcinus orca. That is a definite advantage to being the biggest creature in the ocean. Great job! I read the article about the whales and saw the video. Everything is incredible. Super nice job you did here.
