Mysterious New Whale Species Discovered in Alaska

研究職員以為,該生物現實上是一種管水母目生物,學名Bathyphysa conifera。國度海洋研究中心已經與近海石油和自然氣公司睜開相助,網絡ROV拍攝到的相同視頻。管水母目生物的家屬很大,包羅珊瑚和水母,它們不屬于單體生物,現實上是由成千上萬的生物組合而成。


according to the British "Daily Mail" August 12, reports, near the coast of Angola recently discovered jellyfish like creatures of the deep, dubbed the "Flying Spaghetti Monster" (Flying Spaghetti Monster).


The creature was found in the 1219 meter deep sea of the Atlantic, the British Petroleum Corporation , the oil rig, ROV, and its body has numerous appendages. Staff on the end is what is very confused, and finally named flying noodles monster". Now, the video has been sent to the National Marine Research Center in Southampton, UK, for more scientific recognition.

The researchers think, the creature is actually a mesh tube jellyfish creatures, Bathyphysa conifera. The National Center for ocean research has collaborated with offshore Oil Natural Gas Corp to collect similar video from ROV. The family, which is a family of corals and jellyfish, is not a single organism, but a combination of thousands of creatures.

Like many good mysteries, this one started with a corpse, but the body in question was 24 feet (7.3 meters) long.

The remains floated ashore in June of 2014, in the Pribilof Islands community of St. George, a tiny oasis of rock and grass in the middle of Alaska's Bering Sea. A young biology teacher spotted the carcass half-buried in sand on a desolate windswept beach. He alerted a former fur seal researcher who presumed, at first, that she knew what they'd found: a Baird's beaked whale, a large, gray, deep-diving creature that occasionally washes in dead with the tide.

But a closer examination later showed that the flesh was too dark, the dorsal fin too big and floppy. The animal was too short to be an adult, but its teeth were worn and yellowed with age.

It turns out, according to new research published Tuesday, that this was not a Baird's beaked whale at all, but an entirely new species—a smaller, odd-shaped black cetacean that Japanese fishermen have long called karasu, or raven.

betway必威手機用戶端,"We don't know how many there are, where they're typically found, anything," says Phillip Morin, a molecular geneticist at the National Oceanic and Atmospheric Administration's Southwest Fisheries Science Center. "But we're going to start looking.”

It’s rare to uncover a new species of whale. Advances in DNA research have helped scientists identify five new cetaceans in the past 15 years but two were dolphins and most were simple category splits between fairly similar species. This animal, in the genus Berardius, looks far different than its nearest relative and inhabits an area of the North Pacific where marine mammal research has been conducted for decades.

"It's a really big deal," says study co-author Paul Wade of NOAA's National Marine Mammal Laboratory. "If you think about it, on land, discovery of new species of large mammals is exceptionally rare. It just doesn't happen very often. It's quite remarkable.”


Morin and his team examined the St. George carcass, took bone powder from old museum specimens, and reviewed DNA tests of whales from the Sea of Okhotsk. They studied skulls and beaks and analyzed records from whaling fleets in Japan. They even tracked down a skeleton hanging from the ceiling in a high school gymnasium in the Aleutian Islands.

The scientists conclude in their study published in Marine Mammal Science that this type of whale, which has not yet been named, is nearly as far removed genetically from the Northern Hemisphere's Baird's beaked whales as it is from its closest known relative, Arnoux's beaked whales, which swim in the Antarctic Ocean. The differences, in fact, are so dramatic that the animal has to be something else, they say.

"It's just so exciting to think that in 2016 we're still discovering things in our world—even mammals that are more than 20 feet long," Morin says.

He is not alone in his enthusiasm. Robert Pitman serves on a taxonomy committee for the Society for Marine Mammalogy, which publishes an annual list of all recognized marine mammal species. He is not among the 16 co-authors on Morin's paper. But at a time when the diversity of marine mammals is shrinking—the Yangtze River dolphin is now functionally extinct and Mexico’s vaquita porpoise is dangerously close—Pitman calls the discovery "heartening."

"It boggles my mind to think that a large, very different-looking whale has gone unnoticed by the scientific community for so long," Pitman says. "It sends a clear message about how little we know about what is in the ocean around us." The discovery also raises new questions about how well humans are understanding the threats posed by marine activities, from energy exploration to sonar use, given that so few people even knew such a creature existed.
