Hi Guys, Welcome to my Blog. This is my first Article. Today I am going to write about 10 Enormous Facts about Blue Whales. Blue whales are most probably one of the most wonderful creatures of this Universe. Their sheer size and extremely peaceful lives are certain to fill anyone with wonder, amazement and immense respect, even if they are not particularly animal lovers. Even though they are such big animals, very less evidence has been found about them and many things, social and physical, still remain a mystery. But, what little we know is quiet enough to amaze us. So, here are some details about blue whales that we are sure you would like reading about.
1. Even when taking dinosaurs into account, the modern day blue whale is the biggest animal to ever exist on Earth:
The sauropods, with their extended necks that could extent tree tops and their long tails, are deliberated the biggest of dinosaurs. From the tip of their mouths to the tip of their tails they measure between 80 to 130 feet and can evaluate up to 96.4 tonnes. Blue whales, on the other hand, measure up to 98 feet to 106 feet long with the extreme recorded weight being 173 tonnes, and might perhaps reach 181 tonnes. Associated to blue whales, sauropods are thinner and weigh much less. It is possible that being in water has allowed whales to continue their large size without bearing the brunt of gravity, a persuading factor in the evolution of land animals. Their large fat filled bodies enjoy resistance in water which stops them from failing under their own weight.
2. A blue whale’s tongue weighs as much as an African forest elephant and its heart is at least the size of a golf cart:
The biggest of animals has the weightiest of tongue and weighs around 2.7 tonnes, which is around the same weight as an African forest elephant, though biggest of these elephants, are known to gain as much as 6 tonnes. Though there are statements that a blue whale’s heart being as big as a car, so far they could not be verified allowing for the difficulty in locating a proper specimen that was intact. Whether a whale larger than that could have a heart the size of a car is not known.Image Source: www.unbelievable-facts.com
3. Blue whales can eat 500 kilograms of krill in a single mouthful and get half a million calories from it. That’s 200 times of what they occupy in the act:
Blue whales consume almost entirely on krill, small shrimp-like creatures, and a small number of copepods, small fish, crustaceans and squid that get into their mouth. The mouths, when fully extended, are large enough to hold 90 tonnes of food and water. During their feeding time, they open their mouths wide and lunge at the krill. Then they close their mouths and push the water out through baleen, the bristle-like constructions made of keratin present on the edge of higher jaws. If the krill group is dense enough, an adult whale can gulp up to 500 kilograms of krill, that’s 457,000 calories, in only mouthful. In a day, an adult whale can consume 40 million krill.
4. Blue whales are regular feeders. They can go up to 6 months without eating when they travel for breeding:
The largest inhabitants of krill are found in the Antarctic and establish the main food source for seals, penguins, fish, squid, as well as whales. As they gain more vitality than they spend they build substantial energy reserves. They devote these reserves when traveling for breeding to warmer parts of the oceans near the equator, where krill is scarce
5. Blue whales are born massive as well. Their calves weigh 2.5 tones at birth, gain 8 lbs per hour and grow at a rate of 1.5 inches per day:
The female blue whales naturally give birth every two or three years at the twitch of winter and have a gestation period of 10 to 12 months. Their calves weigh about 2.5 tonnes at birth and are 7 meters (23 feet) long. In a day they swill about 380 to 570 liters of milk, which has vitality content of 4,370 kilo calories per Kg. The calf doubles in size in just six months by which time they are stopped.
