Giant Squid Blinds Prey During Attack.

As they attack their prey, giant deep sea squids use an unusual weapon: blinding bright lights to disorient their victims.

The footage reveals the creatures emitting short flashes from light-producing organs, called photophores, on their arms.

Writing in Proceedings of the Royal Society B, the team said: "[The bioluminescence] might act as a blinding flash for prey."
