I like your videos Sir. You are about the first spear-fisher I have seen do as many Octopus as you do. Interesting. I do scuba and had opportunity to "play" with two Giant Octopus in the Puget Sound a few years back. Heads nearly as big as basket balls. Amazing creatures. Rock on.
Nice Vid. With tako, you have to be the negotiator and not the S.W.A.T.. Poking violently makes it very difficult to get out, but just do it gently and try get behind or under and coax them out. Once they pop out, then you can pounce :)
