Mystery 200-year-old Shipwreck Discovered in Gulf of Mexico

Mystery 200-year-old Shipwreck Discovered in Gulf of Mexico Archaeologists think the boat may have met a fiery end.

The new species was caught in February 2010 during a study of sperm whales in the Gulf of Mexico and was described in the animal taxonomy journal Zootaxa. “ In the history of fisheries science, only two pocket sharks have ever been captured or reported,” study author Mark Grace said.

The 5 1/2-inch American Pocket Shark is the first of its kind to be discovered in the Gulf of Mexico , according to a new Tulane University study. According to the paper, the shark secretes a glowing fluid from a tiny pocket gland near its front fins. It's thought to help attract prey, who are drawn to the

Think sharks are all big and scary? Think again. Scientists have just discovered a new species of pocket shark in the Gulf of Mexico, which is just 5½ inches long.

They have named it the American pocket shark, or Mollisquama mississippiensis (pronounced mah-lihs-KWAH-muh MISS-ih-sip-ee-EHN-sis, according to AP.)

The shark has several unusual features that are described in the journal Zootaxa, including a pouch near the front of its fins which squirts out puffs of glowing bioluminous fluid clouds, and light-producing photophores - glands that look like little lights - all over its body.

The 5 1/2-inch American Pocket Shark is the first of its kind to be discovered in the Gulf of Mexico , according to a new Tulane University study. Scientists stumbled upon a teeny male kitefin shark in 2010 while studying sperm whales in the Gulf . It wasn't observed again until 2013, when National

"In the history of fisheries science, only two pocket sharks have ever been captured or reported," said Mark Grace from the NMFS Mississippi Laboratories of the National Oceanic and Atmospheric Administration (NOAA).

"Both are separate species, each from separate oceans. Both are exceedingly rare."

The other pocket shark was discovered in Peru and is 16 inches long. The new species differs in that it might have a special pressure-sensitive organ that detects movement hundreds of feet away, and it might also have fewer vertebrae.

Henry Bart from Tulane University in Louisiana added that the unique shark only further proves how little researchers know about the deep waters of the Gulf, and that "many additional new species from these waters await discovery."

This pocket shark (Mollisquama mississippiensis) was discovered in the central Gulf of Mexico in February 2010. It has just been classified as a new species and is one of only two pocket sharks ever found. " In the history of fisheries science, only two pocket sharks have ever been captured or

The tiny shark was actually collected in 2010, but it wasn't until Grace was examining specimens in 2013 that he saw it and decided to work out what species it was with Bart and Michael Doosey from Tulane University. Other authors of the study include John S. Denton and Gavin Taylor from the University of Florida, and John Maisey from the American Museum of Natural History in New York.

They used a dissecting microscope, x-ray images, and a high-resolution CT scan to examine and photograph the specimen.

These Sharks Glow Green in the Dark and Scientists Now Know Why.
Scientists have identified a substance that enables some sharks to give off a bright green glow, which they believe only other sharks can see. The authors of the paper, published in the journal iScience, previously showed that swell sharks—who live in California's Monterey Bay to southern Mexico and the coast of Chile—are biofluorescent. That means they soak up light—in this case ambient blue ocean light—and use it to give off light in a different color, usually green, red or orange. In their latest study, researchers wanted to learn more about what being biofluorescent means for these creatures.
