The first live telecasting of the rich - ocean eight - arm calamary in its instinctive environment divulge it to be a fast , aggressive marauder that flashes light shows potentially to blind quarry or woo married person .
Zoologist Tsunemi Kubodera at Japan ’s National Science Museum in Tokyo and his colleagues , the same researchers who catch the first unrecorded gargantuan calamary ( Architeuthis)footage two long time ago , recorded the deep - sea eight - armed squidTaningia danaeusing a newly developed underwater high - definition video recording tv camera organisation .

The deep - sea eight - armed squid is the turgid known bioluminescent or light - emitting creature in the world . The largest be intimate specimen grows up to 7.5 - foot long and 130 pound . , with eyes the size of enceinte grapefruit . Hundreds of their beaks have been found in sperm whale stomachs , suggesting these are very abundant in tropic and subtropical ocean .
The researchers cover the squid off the Ogasawara Islands , some 600 mi south of Tokyo . They suspend their cameras from about 750 to 3,000 feet deep , and on a rod attached to the cameras , Kubodera and his fellow dangled tiny flashlight and sweetener , either a smaller calamary or a mackerel .
The calamary course possess many petite dental caries of ammonia answer within its form to help maintain perkiness , pull in the bodies of enamor specimen flabby and indulgent to the feeling . This led scientists to suspect it move sluggishly .

Kubodera and his fellow worker speculate these flashes might blind prey or help the squids measure distance to their targets in the dark depths of the sea .
As the squid wandered around the red torch attached to the bait rig , the scientists also saw the animals pulsate long and unretentive glows . These might be attempt at communicating or even " potentialcourtshipbehaviors , " Kubodera and his confrere spell .
