NEW YORK (AP) — Whales are big, but why aren't they bigger? A new study says it's basically about how many calories they can take in. That's the conclusion of researchers who used small boats to chase down 300 whales of various species around the world. They reached out with a long pole to attach...

This Nov. 20, 2019 photo provided by Oregon State University shows the skull from a blue whale skeleton being transferred to a trailer after pulling it from Yaquina Bay, Newport, Ore. The carcass of a giant blue whale that's been submerged off the Oregon coast for more than three years was hauled to the surface so it can be reassembled, studied and put on public display, scientists with Oregon State University said Friday. The dead whale, which was about as long as two school buses, washed ashore near Gold Beach, Oregon in 2015. It's exceptionally rare to see an intact blue whale carcass wash ashore and the only other documented case happened more than 200 years ago, when the Lewis and Clark expedition noted that they saw Native Americans salvaging edible parts from a blue whale, said Bruce Mate, emeritus director of Oregon State University's Marine Mammal Institute.

FILE - This April 14, 2019 file photo shows a western meadowlark in the Rocky Mountain Arsenal National Wildlife Refuge in Commerce City, Colo. According to a study released on Thursday, Sept. 19, 2019, North America’s skies are lonelier and quieter as nearly 3 billion fewer wild birds soar in the air than in 1970. Some of the most common and recognizable birds are taking the biggest hits, even though they are not near disappearing yet. The population of eastern meadowlarks has shriveled by more than three-quarters with the western meadowlark nearly as hard hit. (AP Photo/David Zalubowski, File)

A pocket-sized pocket shark found in the Gulf of Mexico has turned out to be a new species, and one that squirts little glowing clouds into the ocean. Researchers from around the Gulf and in New York have named it the American pocket shark, or Mollisquama (mah-lihs-KWAH-muh) mississippiensis (MISS-ih-SIP-ee-EHN-sis).
