Abstract

The registration of reproductive processes of elasmobranchs is rare and little documented in public aquariums. The present work registers the first case of dystocia in cownose ray (Rhinoptera bonasus), (Mitchill, 1815). The ray maintained in captivity by 16 years, it presented a gestation of 14 months. There was not occurrence of the natural childbirth, being necessary the human intervention through obstetric maneuvers for the retreat of the fetus. The described procedures can be used as reference in other cases of dystocia with the species.
