WASHINGTON (AP) — For decades, there were tales from fishermen and tourists, even lots of photos, of a mysterious killer whale that just didn't look like all the others, but scientists had never seen one.Now they have.An international team of researchers says they found a couple dozen of these distinctly different orcas roaming in the oceans off southern Chile in January. Scientists are waiting for DNA tests from a tissue sample but think it may be a distinct species.The National Oceanic and Atmospheric Administration felt confident enough to trumpet the discovery of the long rumored killer whale on Thursday. Some outside experts were more cautious, acknowledging the whales are different, but saying they'd wait for the test results to answer the species question."This is the most different looking killer whale I've ever seen," said Robert Pitman, a NOAA marine ecologist in San Diego. He was part of the team that spotted the orcas off Cape Horn at the tip of South America.How different? The whale's signature large white eye patch is tiny on these new guys, barely noticeable. Their heads are a bit more rounded and less sleek than normal killer whales and their dorsal fins are narrower and pointed.They likely mostly eat fish, not marine mammals like seals, as other killer whales do, Pitman said. Fishermen have complained about how good they are at poaching off fishing lines, snatching 200-pound fish away.Pitman said they are so different they probably can't breed with other killer whales and are likely a new species. At 20 to 25 feet long (6 to 7.5 meters), they are slightly smaller than most killer whales. In the Southern Hemisphere, killer whales are considered all one species, classified in types A through C. This one is called type D or subantarctic killer whales.Michael McGowen, marine mammal curator at the Smithsonian, said calling it a new species without genetic data may be premature. Still, he said, "I think it's pretty remarkable that there are still many things out there in the ocean like a huge killer whale that we don't know about."Scientists have heard about these distinctive whales ever since a mass stranding in New Zealand in 1955. Scientists initially thought it could be one family of killer whales that had a specific mutation, but the January discovery and all the photos in between point to a different type, Pitman said.He said they are hard to find because they live far south and away from shore, unlike most killer whales."The type D killer whale lives in the most inhospitable waters on the planet. It's a good place to hide."Pitman got interested in this mysterious killer whale when he was shown a photograph in 2005. When he and others decided to go find them, they followed the advice and directions of South American fishermen, who had seen the whales poaching their fish.After weeks of waiting, about 25 of the whales came up to the scientist's boat, looking like they expected to be fed. Equipment problems prevented the scientists from recording enough of the whale songs, but they used a crossbow to get a tissue sample. Pitman said the whales are so big and their skin so tough that it didn't hurt them, saying the arrow "is like a soda straw bouncing off a truck tire."Pitman said he'll never forget Jan. 21 when he finally saw his first and then a bunch of the type D orcas."For 14 years I was looking for these guys. I finally got to see them," Pitman said.He acknowledged that he did sound like the revenge-seeking captain in the classic novel "Moby-Dick.""I guess I know how Ahab felt, but for a good reason," Pitman said. 3606

WASHINGTON — Congress is defying President Donald Trump on removing Confederate symbolism from the military.The Senate on Thursday joined the House in approving legislation that would rename bases like Fort Bragg and Fort Benning that are named for Confederate officers.The Senate vote was an overwhelming 86-14 vote. Earlier this week, the House passed the measure with a 295-125 vote.The Senate passage opens the door for the Senate and House Armed Services Committees to open negotiations for a final version of the bill. Once that bill is passed, it would head to Trump's desk.Even if Trump were to veto the bill, Thursday's vote indicates that Congress could override it and make the bill a law.Trump has said he favors that military bases keep the names of Confederate military leaders, despite efforts from Pentagon officials to change the name. Trump says renaming the bases would be re-writing history; critics say it's inappropriate for U.S. military bases to bear the names of those who fought on the side of slavery and against the Union.There are currently 10 Army bases throughout the U.S. named after Confederate generals, as well as a number of smaller military institutions with such names.The legislation would approve 1 billion in spending for the military and also includes a 3% pay raise for the troops. 1335

WASHINGTON (AP) — Navy officials said Wednesday they are pulling achievement medals from prosecutors who argued the case against a decorated Navy SEAL who was acquitted in the death of a wounded Islamic State captive after President Donald Trump intervened.Trump tweeted earlier Wednesday that he had directed the secretary of the Navy and the chief of naval operations to "immediately withdraw and rescind" the Navy Achievement Medal from prosecutors who argued the case against Special Operations Chief Edward Gallagher, who was acquitted by military jurors earlier this month."The Prosecutors who lost the case against SEAL Eddie Gallagher (who I released from solitary confinement so he could fight his case properly), were ridiculously given a Navy Achievement Medal," Trump complained, adding, "I am very happy for Eddie Gallagher and his family!"Navy spokesman Cdr. Jereal Dorsey said that on Wednesday, after Trump's tweet, Navy Secretary Richard Spencer rescinded the awards. As secretary, he has that authority, Dorsey said. 1042

WASHINGTON — The number of Americans seeking unemployment benefits fell slightly last week to 751,000, a still-historically high level that shows that many employers keep cutting jobs in the face of the accelerating pandemic. A surge in viral cases and Congress’ failure so far to provide more aid for struggling individuals and businesses are threatening to deepen Americans’ economic pain. Eight months after the pandemic flattened the economy, weekly jobless claims still point to a stream of layoffs. Before the virus struck in March, the weekly figure had remained below 300,000 for more than five straight years. 626
