The crew was elated by the 25-second clip and reached out to Michael Vecchione, a cephalopod expert with NOAA at the Smithsonian National Museum of Natural History, to confirm what they'd seen was indeed a giant squid.
This 25-seconds of footage is significant because scientists still know relatively little about the giant squid. Most of the information is cobbled together from specimens that have washed ashore rather than actual observation of the squid in its habitat.
The squid was attracted to a specialized LED light developed by marine biologist Edie Widder. The lights mimic a glowing jellyfish in distress, something that can attract larger predators to take care of the smaller predator molesting the jellyfish. This device, the Medusa, is the same one that Widder used when she was part of a crew that filmed a giant squid for the first time ever near Japan. The light is attached to a low-light camera in an effort to not scare off the wildlife with the engines of larger vehicles.
