Octopus-squid with world's largest 'headlights' attacks camera under sea

The world's most elusive squid species showed a brightening bioluminescent display as it attacked an underwater camera in the deep sea.

The rare encounter, which took place around 3,281 feet (1,000 metres) below the Pacific Ocean's surface, was observed by the researchers belonging to the Minderoo Foundation and the University of Western Australia (UWA) Deep Sea Research Center, according to Live Science.

When the team spotted the rare creature, they were on a research cruise documenting the diversity of the deepest part of the ocean.

The animal was found to be Dana octopus squid (Taningia danae), which is a member of the family Octopoteuthidae. It feeds on pelagic fish, crustaceans and other squid species.

Within the Octopoteuthidae family, squid species have eight arms which is why they are known as octopus squid. In addition to their arms, they have two long, trailing tentacles as juveniles. However, these are lost as the squid matures.

Members of this species are popular for their big size. According to a 2003 study, the longest individual ever reported was a 7.5-foot-long (2.3 m) female.
