Pocket-sized shark squirts glowing clouds from pockets

NEW ORLEANS (AP) — A pocket-sized pocket shark found in the Gulf of Mexico has turned out to be a new species.

And the mysterious pouches that it’s named for, up near its front fins? Scientists say they squirt little glowing clouds into the ocean.
====================================================
Scientists have named the new shark Mollisquama (mah-lihs-KWAH-muh) mississippiensis (MISS-ih-sip-ee-EHN-sis), or the Mississippi pocket shark.

'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. He said the other two are the previously known pocket shark and the taillight shark , which has a similar gland near its tail.'

The taillight shark (Euprotomicroides zantedeschia) emits a luminous bluish fluid of unknown biology & chemistry.

WOW, it's amazing how much we really don't know.

I wonder how many species we have driven to extinction without even knowing they existed???

Watch Trump's buddy in Brazil & see what's left of the rain forest after he gets finished with it. Hundreds of species & entire primitive tribes will be destroyed.
 
Such bio-luminescence is usually to disguise a signature seen from below and resulting from natural light. Creating light underneath itself masks its presence to animals below.
 
Just when we thought it was safe to go back in the water...

No evidence yet that this is bioluminescence. Could be biofluoresence, molecules getting excited by photons from sun light.

Animals use bioluminescence to communicate or attract prey.

Midwater fish don't use it for prey that I'm aware of.
