Not more than two weeks ago I watched a PBS program on this same Japanese team, where they photographed a female squid, which had gotten hooked on the bait they were using to lure a giant squid in. After being hooked for a considerably lengthy period of time, that squid chewed through the tentacle that was snagged, and the Japanese crew eventually retrieved the line with 15 foot tentacle still attached. This same team has been working at this for 3 years, or so. They had figured out, by the movement of feeding whales (the whales feed on the giant squid) and how deep they were when they were feeding, where they would find the squid--turns out the depth of the squid was in a very narrow range of depths, i.e. between 2,000 and 2,300 feet, so that 300 feet is where they set-up their cameras, lights, bait, etc. to be the first to film the giant squid, and then be the first to capture one, but again, it took them years of dedication. It's pretty fascinating, as the giant squid have been known about forever, but never filmed, or intentionally caught.
