A New Record in a Well-Established Population ofOctopus hubbsorum(Cephalopoda: Octopodidae) Expands its Known Geographic Distribution Range and Maximum Size

Researchers document a new record of Octopus hubbsorum, expanding its known geographic distribution to include Bahía Magdalena on Mexico's Baja California peninsula. This discovery extends the species' range further north into temperate zones and significantly increases its maximum recorded size (1020 mm total length, 220 mm mantle length, 3705 g weight). The study confirms a well-established population in this region, providing critical insights for fishery management and conservation efforts. Observations were conducted in intertidal and subtidal zones up to 30 meters deep, leveraging field surveys and morphological measurements to validate the findings.
