“All chimaeroid fishes are oviparous. Males possess elaborate copulatory organs on their pelvic fins, which they use to transfer sperm to the female oviducts. Males also possess 2 additional organs used copulation. Unique to chimaeroids is a club-like frontal tenaculum armed with multiple rows of denticles which emerges from the top of the head in sexually mature males. It has been observed that the frontal tenaculum is used to
grasp the posterior edge of the pectoral fin of the female to aid in positioning the male during copulation. “
