Octopus hubbsorum Berry, 1953 is an important fishery species off the Pacific coast of Mexico. It inhabits the intertidal and subtidal zones to depths of 30 m. Its occurrence has been documented in tropical and subtropical zones. In Mexico, it is in the Gulf of California and at some localities of the southern Mexican Pacific, including the Revillagigedo Islands. In this paper, the presence of a well-established population of O. hubbsorum in Bahia Magdalena (on the west coast of the Baja California peninsula) is presented. This new record expands the distribution range not only in distance but also into a temperate zone. Additionally, the maximum size records for this species are extended (1020 mm total length; 220 mm dorsal mantle length; and 3705 g total weight).
