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

Three American tourists, including a married couple, drowned in Turks and Caicos, the group of islands southeast of the Bahamas, authorities and local reports said.Two girls survived what authorities called a "very human and terrible tragedy" in the waters off scenic Bambarra Beach in Middle Caicos on Monday. One of the children was the daughter of the couple who drowned, authorities said, while the other girl was related to the third victim."We are saddened whenever incidents of this nature occur," Ralph Higgs, the Minister of Tourism, said in a written statement.Authorities said the two families went to the beach and encountered a fast-moving tide.Many in the community pitched in to help the extensive search on land and water."We came together as a community and we tried our best," Frederico Johnson, a district commissioner in Middle Caicos, told local station PTV8 News Watch.Johnson, who set out on foot and helped search the beach, said that after two bodies were found Monday, he was scanning for any sign of a person. "Right when I was about to leave, I saw this shape in the water" on Tuesday, he told PTV8.Police Commissioner Trevor Botting praised Johnson for his efforts, saying, "Your acts of leadership speak volumes."Authorities have not released the identities of the victims pending notification of kin.CNN confirmed with a relative of one of the victims that the three were Americans visiting the island. The relative had posted on Facebook that her "heart was BROKEN!!!" She told CNN the family was grieving and did not want to comment. 1578

The Transportation Security Administration (TSA) recovered more guns at airports across the country in 2019 than ever before in the agency's history.According to TSA, 4,432 firearms were discovered in carry-on bags or on passengers at checkpoints across the country. Of those, TSA says 87% were loaded."The continued increase in the number of firearms that travelers bring to airport checkpoints is deeply troubling," TSA Administrator David Pekoske said. "There is a proper way to travel safely with a firearm. First and foremost, it should be unloaded. Then it should be packed in a hard-sided locked case, taken to the airline check-in counter to be declared, and checked."TSA recovered the most guns at these 10 airports:Hartsfield-Jackson Atlanta International — 323 firearms recoveredDallas/Fort Worth International — 217 firearms recoveredDenver International — 140 firearms recoveredGeorge Bush Intercontinental — 138 firearms recoveredPhoenix Sky Harbor International — 132 firearms recoveredDallas Love Field — 103 firearms recoveredFort Lauderdale-Hollywood International Airport — 100 firearms recoveredNashville International Airport — 97 firearms recoveredOrlando International Airport — 96 firearms recoveredTampa International — 87 firearms recoveredTravelers who bring firearms to checkpoints could face criminal charges and federal civil penalties of up to ,000. TSA says a typical first offense for carrying a handgun into a checkpoint is ,100. 1481
