Newly discovered shark species pours flickering clouds out of pockets



A small shark found in the Gulf of Mexico with mysterious bags near its front fins has turned out to be a new species, scientists say.

An appropriately called American pocket shark, or Mollisquama mississippiensis, uses the bags to make small clouds in the ocean. Only a third type of shark of more than 500 can absorb light fluid, according to a University of Florida scientist who has not participated in the study. The other two are the previously known pocket shark and rear shark light, which has a similar gland close to its tail. told Associated Press. "This shows us how little we really know."

The new shark was discovered by Mark Grace, an Ichthyologist at the National University. Ocean and Atmospheric Administration (NOAA). He has gathered a baby of a species during a 201

0 study to find out what the Gulf of Mexico gallop is eating through trolling in an area and at depth where well-marked whales are fed.

He told the AP that the American pocket shark was in the last specimen bag he discovered about three years later. "I'm in science for about 40 years," he said. "I can usually do pretty good guesses, I could not do that, I thought I was doing something wrong." On the other hand, the American pocket shark discovered by Grace was a 5.6-inch-new-born male. the muscles are lined with fluorescent projections coated with pigment, which indicates that they are a jet of light fluid, "says Grace and his collaborators in the journal Zootaxa. The shark also has clusters of light-emitting cells placed on the abdomen.

They identified the shark as the second of its kind. It took years more, including high-resolution scanning in the particle accelerator in Grenoble, France, to get more internal details to make sure it is a new look. , made cellular dissection a little, "Grace said," Collaboration was exciting.
