Octopus engineering, intentional and inadvertent
Taylor & Francis Online
David Scheel, P. Godfrey-Smith (@pgs), S. Linquist, S. Chancellor, M. Hing & M. Lawrence

We previously published a description of discovery of a site where octopuses live in an unusually dense collection of individual dens near one another in a bed of scallop shells amid a rock outcrop. We believe the shell bed is an extended midden, accumulated over time by individual octopuses returning to their dens with food. Here we consider what aspects of material collection, den maintenance, and aggregation are intentional for the octopuses, versus inadvertent consequences of individual decisions. Collection of prey items, transport of prey to the den, den excavation, and collection and use of non-prey materials at the den appear to be intentional behaviors. The occurrence of many dens in close aggregation appears to be an inadvertent outcome of the availability of food and the risk of predation in the habitat. Popular media reports have described this site as an ‘city’ designed by octopuses, but that is not an accurate description of the site.

Cephalopods in Action
Vecchione, Michael and Clyde F.E. Roper 1991

Cephalopods observed from submersibles in the western North Atlantic.
Bulletin of Marine Science, 49(1-2):433-445.

ABSTRACT: Records of 158 observations of cephalopods from submersibles, primarily the JOHNSON SEA-LINK, have been compiled through collaboration with several investigators. These observations include 118 videotape sequences, 58 collected specimens, and numerous shipboard photographs of live animals. At least 33 species have been observed to date; a few species have been observed repeatedly and could be good subjects for directed studies. The methods developed for in situ observation and subsequent collection of specimens with little or no damage allow descriptions of behavior, morphology, physiology, and distribution that are not possible with other methods of collecting.
