One of the rarest creatures on earth have appeared in the Atlantic Ocean. The animal is endangered Right whales to extinction because of hunting in the 19th century and 20.
Experts trace the large marine mammals and said almost half of the global population, which is about 500 or more, have been found in the Gulf of Cape Cod, near the state of Massachusetts, during last spring.
They returned again in the same amount and make the amateur photographers and scientists were surprised.
"This is extraordinary and very surprising," said senior scientist and chairman of the Right Whale Ecology Federally-Funded Center for Coastal Studies in Provincetown, Charles "Stormy" Mayo.
North Atlantic Right whales have been hunted for centuries in Cape Cod Bay. As a result, their numbers continue to decline due to hunting and the use of oil and bones from these animals.
But lately, they are rarely seen in that place. "At the end of the 1990s, less than 30 whales are seen every year," said Mayo, who has researched Right whales and the ecosystem since 1984.
"There has been a large increase in the appearance of these animals in recent years," said a scientist who works closely with the New England Aquarium's Right Whale Project Reasearch, Amy Knowlton.
"Right whales may be traveling in search of food all the time. When one of them find it, then he would call his friends," said Amy.
Each whale has a unique mark on his head and a distinctive V-shaped bursts of callosty or blowholes. It made the researchers used to identify and record it. As quoted by News.com.au on giving these animals with funny names such as Kleenex, Snotnose, and Wart.

Their presence is often enough in the Gulf of Cape Cod has made scientists were surprised. Mayo believes it happened because of shifts in ocean currents which might be due to global climate change. As a result, brings more plankton into the bay. Even the Right whales normally find food off the coast of Maine has been reduced.
"They are like cattle in the pastures. Animals were going away from the place that is not good towards a better location," he said.
Though some Right whales arrive in the bay in early December and was there until mid-May, their appearance will usually increase in March and mid-April, when the concentration of plankton being at the highest level.
However, the busy waters have apparent danger, namely the risk of getting hit by a commercial ship and travel, or entangled in the net.
Researchers reported the existence of these whales to the state and federal governments. Federal law prohibits ships approaching at a distance of 500 yards or 457.2 meters from the presence of the pope and obliging to slow down the speed up to 10 knots, or 18.52 kilometers per hour.
"It's nice every time we see and know that they are alive," said Knowlton.
"By seeing and observing their scars, we can really understand what happens to the animals."
Right whales are slow swimmers reply. Therefore, hunters can easily catch them and they are also often swim close to shore. The hunters regard the pope's right ones for the right to hunt or be hunted.
