Resumen:
The reproductive biology of the angel shark Squatina guggenheim was described based on 584 animals caught from San Matías Gulf, Argentina. Males and females reached sexual maturity at 76 and 73 cm of body length respectively. In the case of females, only the left ovary was functional. The maximum follicle diameter recorded (6cm) was observed during autumn and winter (South hemisphere). No post-ovulatory follicles were found and only a few pregnant females were caught. In males, testes were paired and showed diametric development. The results suggested that the San Matías Gulf is not a breeding area for this species.
