Here's The Super Largest Creatures on Earth
IZOKE - The blue whale or Balaenoptera musculus is the scientific language of the sea creatures that are very large and are believed to be living beings who ever lived on the planet , bigger than the biggest dinosaurs . The blue whale ever recorded weighed 181 tons and a length of 33 meters . If placed on the ground , the Blue Whale is equal to a length of 9 family car !
Heart size blue whale is the size of a car , and the blood vessels so big that we could swim in it .
a True Giant
Imagine if we sail in the ocean for the first time, exploring the places that we have never seen, and suddenly we saw the ship in addition to blue whales come to the surface, and its size turned out to be longer than the boat we were riding.
Maybe we will be afraid, especially perhaps because we have never seen a living creature with a size so large, we also do not know what we can do great things, whether he can turn the ship and feed on humans. In fact, we need not fear this giant sea creature.
For thousands of years, sailors rarely see these giant mammals and if they meet with the blue whale, they straight away as soon as possible for fear of occurrence. Certainly understandable to ordinary people like us to feel fear and was was met with this giant-sized creature.
Now, we get to know that the blue whale is completely harmless to humans, and in fact, they have something in common with us, human beings, that they are warm-blooded mammals who must breathe the air.
They are also social animals with complex language and intelligence. And most importantly, the blue whale is not a monster at all, they are a gentle giant that we must respect, admire, and protect.
Gentle giant
In Hollywood movies, often described that animals are giant sea monsters that hurt human evil and bring about its destruction. In the wild, the greatest creatures on planet earth turns are gentle creatures, and not dangerous.
And the opposite is true, blue whales, whale species also other whales, suffered due to human activity, and many to the brink of extinction. Blue whales including one of the much sought after centuries ago.
New in recent years, we begin to appreciate the value of their existence. The US government has put a blue whale as an endangered species. Reporting from Extreme Science, whalers in the 19th and 20th century hunting to near extinction. The days of peak, as many as 29,000 blue whales were slaughtered in 1931 alone.
The staple food of blue whales is krill, though they also eat copepods in small quantities. Zooplankton species is eaten by various blue whale from one ocean to ocean. In the North Atlantic, northern krill, thysanoessa raschii, Thysanoessa inermis and Thysanoessa longicaudatamerupakan common foods. In the South Pacific, Euphausia Pacifica, Thysanoessa inermis, Thysanoessa longipes, Thysanoessa spinifera, Nyctiphanes simplex and Nematoscelis megalops; Antarctic Euphausia superba, Euphausia euphausia crystallorophias and vallentini.
Adult blue whale can eat up as much as 40 million krill per day. They always ate in areas with high concentrations of krill, so sometimes it takes approximately 3,600 kilograms (7,900 lb) of krill in a single day. Blue whales filling their bellies in waters rich in krill in the Antarctic before migrating to breeding grounds in warmer waters and less rich in krill near the equator.
Perhaps one of the most spectacular of the Blue Whale is the sounds they make. Researchers have measured the low-frequency sounds produced by blue whales to communicate with menggunakandecible meters.
Some of their vocalizations teleh as loud as 188 decibels recorded and can be heard as far as 848 km! For comparison, the sound of jet aircraft that was taking off at 120 decibels. Thus, we can conclude that the blue whale is a living creature that is able to produce the loudest sound in the world.
Why the Blue Whale can be sized so big ?
So far, researchers still are not sure why , but they believe with certainty that any of the dinosaurs in the past , they never reached the size of a blue whale . This is the greatest thing that has ever lived on the planet Earth , and is still alive today .
One important reason why whales can reach large sizes is that they have a large living space , a large area to move around and explore. More than 70 % of planet Earth is composed of the oceans .
