Abstract

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.

Abstract

The article presents a study which aims to estimate the age of Commerson's dolphins, Cephalorhynchus c. commersonii, through the growth layer patterns of its teeth. It says that the study used teeth from 198 Commerson's dolphins from the R. Natalie P. Goodall (RNP) collection, formalin, and stereo microscope. Results show that the uniformity and consistency in the teeth growth layer group (GLG) structure can be used to create age determination guidelines for the animal.
