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

Walmart has announced that it will no longer keep "multicultural hair care and beauty products" behind lock and key.The announcement comes as customers raised concerns about the practice.In a statement to E.W. Scripps, the company said about a dozen of its 4,700 stores nationwide placed the products in locked cases.“As a retailer serving millions of customers every day from diverse backgrounds, Walmart does not tolerate discrimination of any kind," the company said in a statement. "Like other retailers, the cases were put in place to deter shoplifters from some products such as electronics, automotive, cosmetics, and other personal care products."According to USA Today, Walmart previously stated that the decision about locking up products came down to individual store managers before the reversal amidst George Floyd protests.“We’re sensitive to the issue and understand the concerns raised by our customers and members of the community and have made the decision to discontinue placing multicultural hair care and beauty products in locked cases," the company said in the statement. 1102

WASHINGTON — The International Monetary Fund has sharply lowered its forecast for global growth this year because it envisions far more severe economic damage from the coronavirus than it did just two months ago. The IMF predicts that the global economy will shrink 4.9% this year, significantly worse than the 3% drop it had estimated in its previous report in April. It would be the worst annual contraction since immediately after World War II. For the United States, the IMF predicts that the nation’s gross domestic product — the value of all goods and services produced in the United States — will plummet 8% this year, even more than its April estimate of a 5.9% drop. 683
