Who is the King of the Earth?

Posted on 04 June 2012 by RE Team

Various animals and species have been capturing the imagination of Humans since the beginning of the civilization due to their majestic powers.  Myhtology and history of Human beings usually referred to various animals as the kings. The limitation on  geographical and biological knowledge caused various civilizations to accept different animals as the King.

We have compiled a list of animals that can be considered as the most powerful in various nature kingdoms. There can’t be an absolute definition to the crown in Natural world, so the list is open for debate!

King of the Animal Kingdom on Land - The Lion has been considered as the King of the animals by most of the civilizations for it’s Majestic look, strength and top predatory nature. But unfortunately once well spread across the globe, the King is currently confined to only African Savannah and India. The Lion can grow beyond 300 kg in weight and 9 feet in length(excluding tail). The mane of the male Lion gives it a royal look making it the King of all the animals. Lion takes the top position in the predator list and no other animal keeps the strength to kill a full grown Lion.

 

Lion - King of the Animals

 

Though Lion is the King of  animals, it lives only in Savannah, there is another distant relative of it who rules the dense Jungles of Earth. Yes, it is the biggest of all big cats, Tiger.  With black stripes on rusty reddish or brown coat and the white fringes around it’s face make the Tiger attractive and very much different from others. A large tiger may weigh more than 350 kg and more than 12 feet in length (excluding tail). Tiger is the most powerful and intelligent hunter in the jungle and is unbeatable.

The King of the sky is the giant Eagles in various part in the world. The Philippine Eagle in South-East Asia, Steller’s Sea Eagle in the coastal region of Asia, The Wedged-tailed Eagle in Australia, Martial Eagle in Africa and Harpy Eagle in America are rulers of the sky in their respective regions. They are expert hunters and the most powerful as no other species can beat them in the sky.  The Steller’s Sea Eagle which the heaviest among them can grow beyond 9 kgs in weight.  These eagles have body lengths of more than 1 meter and can have wingspan of 3 meter (Wedged-tailed and Martial).

The King of the Oceans is Killer Whale or Orca. Though blue whale is the largest animal in the Oceans and White Shark is the largest and sharpest predatory fish, Killer Whale is known to even kill both of them. This mammal is gigantic in size and is equally intelligent and powerful hunter. They are known to hunt seals, sea lions, dolphins and at times large blue and grey whale and also giant white shark. There is no species in the sea water that kill this King.

And at last the King of the whole planet Earth, whether it’s land or water or sky, is Homo Sapien or Human due to their intelligence. No other species can even close human. They are a keepers of the planet and have the responsibility to save all other species.

Hybrid Whale Surprises Scientists

Posted on 26 January 2011 by RE Team

Principal Scientists Kevin Glover at Institute of Marine Research, Norway has revealed a hybrid whale DNA hunted in the northeastern Atlantic in 2007. The whale had the genetic blueprint of a hybrid, with an Antarctic minke mother and Northern minke whale father, Mr Glover came across this surprise while analyzing whale DNA recently.

Soon after Norwegians resumed commercial whale hunting in 1993—following a brief moratorium—the country established a DNA registry to analyze whale kills and help ensure that whale products come from legal sources.

 

Northern Minke Whale

 

After the first analysis, Glover came to know about another similar strange looking whale hunted in 1996 from one of his colleague. It didn’t have the white patch on its pectoral flippers like the northern minke whales do. He suspected this 15 year old whale to be of the same hybrid.

So Glover analyzed the DNA of the 1996 whale captured in the North Atlantic, and found a shocker: It was a pure Antarctic whale. The sample had been overlooked because the DNA archive was in its infancy when the whale was captured.

 

Antarctic Minke Whale

 

This Antarctic whale in the Arctic provided further evidence that Antarctic minkes can migrate to the home waters of their northern relatives and—as the hybrid shows—even mate with them.

Normally the two whale species, Antarctic minke whale and  Northern minke whale, both of which can reach 35 feet (11 meters) in length—undertake seasonal migrations that separate them by many miles of ocean.

Northern minkes head toward the North Pole in spring and ply waters up to the edge of Arctic ice during the summer. In autumn these whales head south, nearly as far as the Equator, to spend the winter.

Antarctic whales follow a similar pattern, moving between Antarctic ice and warmer mid-latitudes with the seasons.

But because the two hemispheres’ seasons are opposite, the minke species don’t share near-equatorial waters at the same time. Thus, they were never thought to meet—until now.

The discovery has now opened new questions to the scientists.  Is the hybrid whale a fluke, or the beginning of a trend? No one knows, but Glover said that his whale biologist colleague Nils Øien has an interesting theory.

Japanese studies showed that the numbers of Antarctic minke in the Southern Hemisphere appeared to drop significantly between the 1980s and 1990s. Other studies show that supplies of the krill—tiny marine crustaceans—that fuel the Antarctic food chain also dropped during this period.

“Japanese research has even shown that the fat layer on whales down there has decreased—not to the point of malnutrition, but suggesting a decreased access to food,” Glover said.

“So we speculate that the amount of krill and available food has decreased, and maybe as a result the whales are starting to go scouting for food.

“It could be that these individuals are straying away from their territory in the search for food, and a few of them may have found their way to the Arctic Circle.”

We hope Scientists will soon come to a conclusion!
