Rare, the flasher deep-sea squid

There are different with squid on this one. It has a bioluminescent glow like a 'spotlight' on the end of her arms, and something that looked like a shiny red lips when passing at close range with a Remotely Operate Vehicle (ROV) in deep ocean waters near Hawaii.

The action caught on camera attached to the ROV operated by the National Oceanic and Atmospheric Association (NOAA) Office of Ocean Exploration and Research. According to a report made by the vessel Okeanos Explorer site, even the squid itself was tether in the ROV and could stay in there for a few minutes.
On Sept. 19, this 1- to 2-meter-long (3.3 to 6.6 feet) squid was captured on video by a remotely operated NOAA vehicle during the craft's descent to the seafloor. (Picture from: http://cbsn.ws/1M3snBE)
Although initially identified by scientists on the ship as whiplash squid, the cephalopods animal was actually a Dana octopus squid or Taningia danae. The size is the same as the whiplash squid, but did not have tentacles to eat that are common in other squid species.

The underwater video 'star' was estimated has a length of 1 to 2 meters. Having a wide and flexible fins out of the squid mantle. With its flap, the organ function of regulating the speed of species T.Danae or Dana Octopus in the water.

On the bottom side of coat seen protruding out something that resembles a red lips. But in fact the unit was functioning removing water from the mantle cavity located behind the animal's eyes and pushed in the opposite direction. This is explained by Scott France, a marine biologist and leader of the expedition along with NOAA, which is also the owner of the voice who gave the explanation in the video.

Although the Dana octopus does not have the tentacles, it had an excess of amazing lighting system called 'photophores'. About the size of a lemon, these photopores is the largest light-producing organs in the animal kingdom today," said Mike Vecchion, a zoologist at NOAA's National Systematics Laboratory at the Smithsonian Institution who is also the curator of cephalopods at the National Museum of Natural History, both located in Washington, DC as quoted from Live Science on Thursday, December 10, 2015.
According Vecchion, squid light beam toward the ROV can support another hypothesis that sea creatures use bioluminescence as a way to lure larger predators attack immediately. The Hohonu Moana expedition lasted from July 10 to September 30, 2015, to investigating the deep sea ecosystems, and take pictures and videos of underwater strange life - small, large, bright or dark - were there. *** [EKA | FROM VARIOUS SOURCES | LIVESCIENCE]
