Monster-size, deep-sea squid that use their glowing arms to blind and stun their prey have been filmed in the wild for the first time, scientists say. The mysterious creatures were videotaped as they hunted deep in the North Pacific Ocean off southeastern Japan.
The footage shows the animals -- Dana octopus squid, or Taningia danae -- targeting prey with bright flashes of light emitted from their arms.
The squid appear to use the tactic to illuminate and stun their victims, writes the team that made the discovery.
Other glowing signals seen from the bioluminescent species may represent a form of communication, possibly for attracting a mate, the researchers add.
