Welcome to The giant Pacific octopus site, devoted to Enteroctopus dofleini, the giant Pacific octopus, in Alaska, where since 1995 I have been studying the ecology and behavior of these octopuses.

An Octopolis photograph helps identify stingarees, added Nov 2013
Kapala Stingaree Peter Godfrey-Smith takes excellent photos, and while I have been attempting to identify the numerous fish that frequent the Octopolis site, this one attracted the attention of the Australian Museum. The Museum has compiled an excellent site that has been very useful in identifying fishes on our Octopolis video.
