This is the extraordinary tale of how a massive, strange-looking fish wound up on a beach on the other side of the world from where it lives.The seven-foot fish washed up at UC Santa Barbara's Coal Oil Point Reserve in Southern California last week. Researchers first thought it was a similar and more common species of sunfish -- until someone posted photos on a nature site and experts weighed in.What transpired after that surprised researchers from California to Australia and New Zealand.It turned out to be a species never seen before in North America. It's called the hoodwinker sunfish."When the clear pictures came through, I thought there was no doubt. This is totally a hoodwinker," said Marianne Nyegaard, a marine scientist who discovered the species in 2017. "I couldn't believe it. I nearly fell out of my chair."How the hoodwinker got its nameNyegaard spent years chasing the hoodwinker sunfish before she located and named the fish. All cases of the big fish were found in Australia, New Zealand, South Africa and Chile, she said. Except for one time in the 1890s, when drawings and records documented the fish appearing in the Netherlands.Scientists say there are five species of saltwater sunfish, and they come from different places. One enjoys tropical waters, another likes the subtropics and the hoodwinker prefers temperate water, Nyegaard told CNN. She works in the marine division at the Auckland War Memorial Museum in New Zealand."This is why it's so intriguing why it has turned up in California," she said. "We know it has the temperate distribution around here and off the coast of Chile, but then how did it cross the equator and turn up by you guys? It's intriguing what made this fish cross the equator."The antics of this wayward fish are comical, especially considering how the species got its name.As Nyegaard researched the fish, she realized some species of sunfish had been misidentified. One species that was thought to be rare was very common, while another fish thought to be common was misidentified, she said."It had gone unnoticed because no one really realized it looked different. There's a long history of confusion about the species in the sunfish family," Nyegaard said. "This fish had managed to stay out of sight and out of everybody's attention. It had been taken for mola mola (an ocean sunfish) so it was hoodwinking us all."And a bit of hoodwinking is what it was doing to researchers in California, too.Scientists first thought it was a different type of sunfishAn intern at Coal Oil Point Reserve alerted conservation specialist Jessica Nielsen to the dead beached sunfish on February 19. When Nielsen first saw it, the unusual features of the fish caught her eye."This is certainly the most remarkable organism I have seen wash up on the beach in my four years at the reserve," Nielsen said in a UC Santa Barbara press release.She posted some photos of the fish on the reserve's Facebook page. When colleague Thomas Turner saw the photos later that day, he rushed to the beach with his wife and young son.Turner, an evolutionary biologist who is six feet tall, stretched out his arms to show the scale of the seven-foot-long fish. He snapped some photos of what he thought was an ocean sunfish, a rare sight up-close, he said."It's the most unusual fish you've ever seen," said the UC Santa Barbara associate professor. "It has no tail. All of its teeth are fused, so it doesn't have any teeth. It's just got this big round opening for a mouth."Turner posted his photos on 3545

The United States is the last country to allow flights of the Boeing 737 MAX fleet after at least 47 countries and multiple airlines grounded the aircraft following Sunday's Ethiopian Airlines crash.At least 271 of the 371 MAX planes in service were grounded, according to CNN calculations. To date, 385 MAX aircraft have been delivered, according to Flight Global, of which 344 are the MAX 8 variant.On Wednesday, Canada joined Egypt, Hong Kong, Lebanon and New Zealand in banning all Boeing MAX aircraft from their airspace as an extra safety precaution, joining scores of nations, carriers and authorities that have temporarily suspended the MAX 8 model or other models in the range.On Wednesday afternoon, Canada's Minister of Transport Marc Garneau said that as the result of new data that they received in the morning, they will no longer allow the Boeing 737 MAX 8 or 9 aircraft to take off or land in Canada, nor will they allow aircraft to fly over Canadian airspace.Six minutes after takeoff, Ethiopian Airlines Flight 302 plummeted into a field, killing all 157 people on board. Shortly after leaving Addis Ababa's Bole International Airport, the pilot reported flight control problems and asked to return to the base.As investigators search for clues into the cause of the disaster, some aviation experts are drawing parallels to the Lion Air Boeing MAX 8 plane that went down last October over the Java Sea in Indonesia, killing all 189 people on board.Both Boeing and the US Federal Aviation Administration (FAA) have said they have no plans to ground the aircraft.The US and Canada are the only countries with MAX 8 flights still allowing the jets to fly. US carriers including American Airlines, Southwest Airlines and United Airlines are flying MAX 8 planes; Air Canada is also continuing to fly its MAX 8 fleet.The MAX 9 model has never crashed, but it was included in an FAA emergency airworthiness directive following the Lion Air crash last year. A MAX 10 model is still in development.China's aviation administration was the first to order a suspension on Monday evening, grounding all domestic Boeing 737 MAX 8 jets, citing its principle of "zero tolerance for safety hazards."China has one of the world's largest fleets of Boeing 737 MAX 8s, operating 97 of the planes, according to Chinese state-run media.The fall-out for Boeing and its future in China could be severe for investors: China is predicted to soon to become the world's first trillion-dollar market for jets.In a statement, Boeing said it continued to have "full confidence" in the safety of the 737 MAX 8 aircraft, but said it understands the decisions made by customers.On its official Twitter account, the company also reiterated that safety remains its priority.Daniel K. Elwell, the acting administrator of the FAA, said it has conducted a review of the Boeing 737 MAX 8 and found "no basis" to ground the aircraft.As more nations ban the 737 MAX 8 planes, Boeing's stock continues a steep slide.Shares in Boeing are more than 10% lower than at Friday's close.As the Ethiopian Airlines and Lion Air crashes are still under investigation, there is no evidence that they had a common cause.The black boxes from the Ethiopian Airlines plane were recovered on Monday, which will enable investigators to learn more about the cause of the crash. On Wednesday, Ethiopian Airlines spokesman Asrat Begashaw told CNN the "black box" data recorders recovered will "definitely be going to Europe," as Ethiopia does not have the necessary equipment to analyze that data.Begashaw said they haven't decided which country the black boxes will go to yet.In the meantime, some aviation experts are focusing on the similarities between the two incidents."Given in both air crashes, the aircrafts were newly delivered Boeing 737 MAX 8, and both accidents occurred during the take-off, they share certain similarities," the Chinese administration said in a statement.Ethiopian Airlines CEO Tewolde GebreMariam told CNN on Tuesday that the company's pilots had received additional training on the flight procedures involving the 737 MAX 8 after the Lion Air crash."We believe the similarities are substantial" between the two crashes, GebreMariam said, adding that both incidents featured new models of the same airplane, and both flights lasted only minutes before the planes went down."We don't yet know the exact cause of the accident, and speculation is not helpful in either way," GebreMariam said, "but I think there are questions without answers on the airplane."Still, aviation safety experts and regulators around the world remain divided on whether the Boeing 737 MAX 8 is safe."I've never said that it's unsafe to fly a particular model of aircraft, but in this case, I'm going to have to go there," David Soucie, a former FAA safety inspector, told CNN, saying passengers don't have enough information.Peter Goelz, a former managing director of the National Transportation Safety Board, said he believes it's too early for American authorities to ground the jets.Some pilots agree. The pilots union at Southwest Airlines, which has the largest fleet of MAX 8s still flying, has stood by the airline's decision.In a Southwest Airlines Pilot Association letter, union president Jonathan Weaks said the union is "extremely confident" that the 737 MAX is safe.He added that he would put his family, friends and loved ones on any Southwest flight, but that he has lobbied for training to "evolve and improve."The letter warns, however, that if new information comes to light, the union "will not hesitate to hold any organization or person accountable." 5654
