Embryonic development of Pachycheles chubutensis (Decapoda: Anomura)

The different stages of embryonic development of the porcellanid crab Pachycheles chubutensis are described, along with the chronology of each stage at 16±1°C. Five different developmental stages (I-V) were recognized including: (i) early cells and 100% of the vitellum; (ii) formation of the embryon...
