| Research Abstract |
Concerning to the mesopelagic large squids, we developed special underwater video camera and lighting system and utilized to observe their natural behavior without disturbing deep-sea environment. In 2011, we successfully observed and recorded live giant squid from submersible off Ogasawara Islands with cooperation of NHK for the first time. On the other hand, we developed multi-logger system and extraordinarily compact underwater camera and attached the logger and camera several times to sperm whales. The logger and camera images gave us a detailed diving trace in 3 dimensions by which casing and hunting behaviour of sperm whales to the prey squid were deduced. In addition, we observed a process of gathering benthic scavengers and clarified chemical attractant and temporal succession of benthic scavenger communities.
