Abstract: Two groups of Octopus rubescens were maintained and observed for space usage in a 3.6 sq. meter tank for one month. Composite regional foraging patterns developed. A pattern of social interactions and body postures reflecting territorial dominance was also observed. Two octopuses were seen to be dominant within indentifiable home ranges. These data suggest that aggressive, dominant O. rubescens may defend a territory.
