Tsunemi Kubodera
is a Japanese zoologist with the National Museum of Nature and Science. On September 30, 2004, Kubodera and his team became the first people to photograph a live giant squid in its natural habitat.〔Kubodera, T. & K. Mori 2005. (First-ever observations of a live giant squid in the wild. ) ''Proceedings of the Royal Society B: Biological Sciences'', 272(1581):2583-2586.〕 Two years later, on December 4, 2006, he also managed to successfully ''film'' a live giant squid for the first time ever.〔(Giant squid caught on video by Japanese scientists )〕 On July 10, 2012, Kubodera, along with two others, become the first to film a giant squid in its natural habitat in a submersible off the Bonin Islands.
In addition to these firsts involving the giant squid, in 2005, Kubodera also became the first to film the Dana octopus squid (''Taningia danae'') in its natural habitat.〔Kubodera, T., Y. Koyama & K. Mori 2006. ''Proceedings of the Royal Society B: Biological Sciences'' (published online). 〕

With his partner Kyoichi Mori of the Ogasawara Whale Watching Association, Kubodera captured photos of the elusive giant squid with his special cameras, after three years of attempts. Relying on the paths of sperm whales, the pair found suitable location to deploy their equipment. The cameras, which were able to store 600 photos, were programmed to flash and take a picture every 30 seconds. Tsunemi's hope was that one of these pictures would contain a photograph of the giant squid. The camera was mounted on a line that used two hooks. To this line Kubodera attached two cuttlefish as bait. The line was then lowered to .〔〔(Holy Squid! Photos Offer First Glimpse of Live Deep-Sea Giant )〕 A giant squid came by, took the bait, and got caught on one of the hook traps. The squid spent 4 hours trying to get free before severing one of its tentacles and fleeing. The tentacle was still moving when the camera was hauled up.〔(Live giant squid caught on camera )〕
The resulting photographs have helped scientists dramatically improve their understanding of giant squid behavior. For example, the squid showed a more aggressive hunting style than scientists had expected.
