Between April 1978 and July 1983 a total of 211 cuttlefish, Sepia officinalis L., was collected in the waters off Plymouth as part of a study of the cuttlebones (Denton & Gilpin-Brown, 1961). The following data were recorded for each specimen: sex, mantle length, the wet weights of the whole animal and the cuttlebone, and for females the weights of the eggs and nidamental glands. The presence of spermatophores in males was also noted. There are rather few records for the winter months; although Sepia were caught at this time they were often required for other studies. It is hoped to obtain more specimens for these months in later years.
