Ommastrephes bartramii and Todarodes filippovae are ommastrephid squids characterized as ‘truly oceanic’ and ‘nerito-oceanic’ species respectively. O. bartramii has a cosmopolitan, discontinuous distribution in subtropical and temperate waters, from surface to 1500 m depth (Dunning, 1998a; Nesis, 1987; Roper et al., 1984). In the South Atlantic it occurs at 14°–27°S in the East (Roeleveld, 1989) and at 27°–45/48°S in the West (Brunetti et al., 1999). Recent reviews on its systematics, distribution and biology (Dunning, 1998a) and its fisheries biology and potential in the southern hemisphere (Dunning, 1998b) and in the Argentine Sea (Brunetti et al., 1999) have been presented. T. filippovae extends from surface to 1200 m depth (Nigmatullin, 1989). It shows a circumpolar distribution in the Southern Ocean, being present in the Antarctic Convergence Zone (Roper et al., 1984 ), in sub-Antarctic waters (mainly 35°–50ºS, up to 17°S in the Peru Current), in Antarctic intermediate waters (up to 33°S in the southeastern Atlantic) (Roeleveld, 1989), in the Subtropical and Subantarctic Fronts (Dunning and Wormuth, 1998; Xavier et al., 1999), and only occasionally in the Argentine Sea (Brunetti et al., 1999). A recent overview on its systematics and biology is given by Dunning and Wormuth (1998). This paper reports the studies on the first specimens of O. bartramii and T. filippovae found alive in Argentine coastal waters. Fil: Re, Maria Edith.
