Sexual dimorphism and morphometric relationships in pelvic bones of Commerson's dolphins ( Cephalorhynchus c. commersonii) from Tierra del Fuego, Argentina.

The article focuses on a study aimed at determining sexual dimorphism across ontogeny in the Commerson's dolphins found in South America. The authors studied more than 300 pelvic bones from male and female Commerson's dolphins. Sex of the dolphins was found by directly observing the genital patch or genital organs during necropsies.
