Resumo: | This study described the reproductive system and gonadal development of Octopus rubescens from Bahía de Todos Santos, Baja California, Mexico. A total of 65 organisms, 35 males weighing 7.2 to 543.4 g and 30 females from 9.4 to 87.7 g where analyzed. The gonad development was defined through histological methods using Hematoxylin-eosin and Arteta- trichrome stains. We describe macroscopically the reproductive system of males and females, and characterized each of the anatomic components. Eight stages of maturity were recognized in females: 1. Immature, 2. Initial folliculogenesis, 3. Final folliculogenesis, 4. Previtelogenesis, 5. Early vitelogenesis, 6. Final vitelogenesis, 7. Maturing and 8. Spawn. In males five stages were identified: 1. Immature, 2. Maturing A, 3. Maturing B, 4. Mature type 1 and 5. Mature type 2. This work is the first histological description of the reproductive system of this species and the beginning for future research on its basic biology.
