This video clip from NHK's "Planet Earth" shows the scene at dinner time on the deep ocean floor. The footage, which appears to have been shot by the Japanese submarine Shinkai 6500 in Okinawan waters at a depth of over 1500 meters (5,000 feet), shows sea-floor scavengers fighting for their piece of a fish carcass that has drifted down to the bottom. Crabs, eels and giant isopods (Bathynomus giganteus), which look like 30 centimeter (1 foot) long wood lice, join in the feeding frenzy that lasts several hours. Here it is time-lapsed to about 20 seconds for maximum impact. Itadakimasu.
