Hi Last year I was workin in on Pemba Island, Tanzania and we were working on local artisanal fisheries one of which was for octopus, specifically Octopus cyanea and can vouch for their size I think the largest caught while we were working on them was 5.7kg it was one of almost 3/4 of a tonne caught over the low tide period last August. I also saw them whilst carrying out Dive surveys in the same area one especially comes to mind that was about 6.5 feet across about 2 meters away from our survey it made me jump I can tell you when it decided to move. So these things can grow to huge sizes. Aside from that does anyone know where I can find Articles or scientific journals about the afore mentioned octopus for work I am trying to do.
Thanks
Kevin
