A biometric analysis of measurement data from a collection of north Queensland dugong skulls, dugong dugon (Muller)

Abstract

Aspects of the size allometry of the dugong skull were examined for 26 variables on a sample of 52 animals using the condylo-premaxillary length as a reference standard. Asymmetry was assessed in four paired variables of the mandible. The relationship between body length and condylo- premaxillary length is described by a second degree polynomial. The condylo-premaxillary length at attainment of sexual maturity is approximately 34 cm.
