The cephalopod family Loliginidae has an important economic value in the small-scale fisheries in Galicia. Early life stages of loliginids are studied off the entire Iberian coast due to their socio-economic importance and to forecast their population abundance appropriately based on the correct identification of the species. Some previous studies carried out in the Ría de Vigo (NW Spain, NE Atlantic) classified the loliginid paralarvae according to morphological characters. Afterwards, molecular analyses using Cytochrome Oxidase I (COI) have shown that most individuals identified as Loligo vulgaris were mislabelled and thus, most of them belonged to the species Alloteuthis media and Alloteutis subulata. To date, the studies were restricted mainly in the south of Galicia. This study will reveal, for the first time, the composition of loliginid paralarvae in the Northern Galician coast. Fifty-five individuals were caught in the North of Galicia during June on board of R/V Sarmiento de Gamboa. Moreover, 153 loliginid paralarvae were collected in South of Galicia on board of R/V Mytilus between June and November. Among these, 51 were obtained in June. This research aims to know the composition of squid paralarvae in the North and South of Galicia based on COI analyses. The results of this investigation will shed light on the distribution, abundance and diversity of loliginids paralarvae along the whole Galician Coast
