Abstract
Aim of the present study was to practically investigate sex in L. vulgaris using choromotophore stripes in both side of the mantle. For this purpose the landings sold in the local fish market (Iskele Harbour, Izmir, Turkey) and L. vulgaris caught by jigging were used (totally 350 squids, 150 males and 200 females; November 2011-June 2012). For sex distinction hectocot-ylized on the distal third of the left ventral arm in male squids and buccal mass under the mouth of the female were used. Finally, this study showed that female and male of L. vulgaris were distinguishable easily based on body pattern.
