Pocket-sized shark squirts glowing clouds from pockets

A pocket-sized pocket shark found in the Gulf of Mexico has turned out to be a new species.Researchers from around the Gulf and in New York have named the species the American pocket shark, or Mollisquama (mah-lihs-KWAH-muh) mississippiensis (MISS-ih-sip-ee-EHN-sis).It's only the third out of more than 500 known shark species that may squirt luminous liquid, said R. Dean Grubbs, a Florida State University scientist who was not involved in the research.
