When Edie Widder saw the giant squid come into view for the first time, its tentacles splayed as it tried to attack the electronic jellyfish lure in front of the underwater camera, she felt a sense of vindication.
After years of trying to develop ways to observe deep-sea animals, the CEO and senior scientist at the Florida-based Ocean Research and Conservation Association (ORCA), had finally figured out the key. The special camera system she developed, called Medusa, emits a red light invisible to most creatures living in “midnight zone,” some 3,280 feet below the ocean’s surface, where it’s pitch black.
