Histological Analysis of the Reproductive System and Gonad Maturity of Octopus rubescens

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 histolo...
