In total, 53 specimens of comb-fin squids (<i>Chtenopteryx</i> spp.) were caught at depths ranging from 30 to 800 m off the Canary Islands (NE Atlantic Ocean). Mantle lengths of the individuals ranged from 18 to 43 mm and the sample included immature, mature male and mature female specimens. Two species of comb-fin squids, <i>Chtenopteryx canariensis</i> and <i>C. sicula</i>, were identified by combining traditional morphological characters with a molecular analysis of a fragment of the cytochrome <i>c</i> oxidase subunit I (COI) gene.
