The distribution of planktonic juveniles Octopus vulgaris were investigated in the Northwestern part of Harima Nada during the period from May 1980 to September 1982. In total, 159 specimens were collected at 8 cruises among 14 cruises or 49 larva-net tows out of 113 in the season between August and December.
Ranges of total length, body weight and sucker counts of the collected specimens are 2.4-13.2mm, 1-110mg and 3-22, respectively.
The planktonic juveniles were collected from only near-bottom layer in daytime, but from both surface and near-bottom at night.
Many specimens were collected from nearshore area rather than from offshore region.
