Seventy\u2010six specimens were collected from the artisanal fisheries using bottom gillnets and trammel nets, targeting mainly elasmobranchs. We determined sex, total length, and external characteristics such as the presence or absence of semen, rotation of the gonopterygia, opening of the rhyphiodon, thorns on the pectoral fins of males, and mating scars on females.

The analyses revealed directional asymmetry in both sexes, with the left ovary and uterus in females, and the left testis and epididymis in males, generally larger than the right counterparts. In addition, reproductive organ size increased significantly with total length.
