A total of 143 organism of Apristurus nasutus (de Buen, 1959), were caught in a research survey at June 2007. The samples were obtained by means of a trawl net at 250 - 460 m depth, in the middle and north part of Gulf of California. This finding represents the first record of Apristurus nasutus in Mexican waters and therefore gives it a wider range the enlargement of his distribution. The specimens caught showed a schooling behavior, most of them in a reproductive stage.
