Historically, the identification of the species of Squatina (Dumeril, 1806) in Uruguayan waters of the Argentine-Uruguayan Common Fishing Zone (AUCFZ) was not clear. During two research surveys carried out onboard of R/V "Aldebaran", on October 1995 and April 1996, 143 tows were performed between 8 and 125 m depth, in order to record the presence of S. guggenheim and S. argentina, and for the first time, indentifying S. occulta in AUCFZ. The taxonomic identification of the species was done under criterions established by Vooren & Da Silva (1991). The external morphological characters employed were: presence or absence of a median dorsal row of spines, shape and size of the pectoral fin and the the dorsal colour pattern
