| A bibliographical review of the taxonomy and biology of the two most important loliginid species, Loligo sanpaulensis and Loligo gahi, of the Argentine Sea is presented. The external morphology and the anatomy of the reproductor system for both sexes are described, as well as the larval period, nutrition, age and growth for both species. The geographical distribution and the relative abundance in relation to the size structure and maturity stage are analized. Abundance estimations of L.gahi, in the Southpatagonian shelf, were obtained from two research cruises data. Catch data for the two species is also presented. |
