An examination of 171 shells of clams (Venerupis philippinarum (Adams & Reeve, 1850)) eaten by Octopus rubescens Berry, 1953 showed that holes in them were drilled by the octopuses preferentially (64.3%) in adductor muscle scar areas (anterior or posterior), which together comprised only 6% of the total shell it area.
