What the skull and scapular morphology of the dugong (Dugong dugon) can tell us: sex, habitat and body length?
Abstract The dugong (Dugong dugon, Müller) is an endangered marine mammal species. We examined the relationship between sex, habitat and body length based on the skull and scapular morphology and morphometrics of 81 dugong samples in Thailand. A total of 58 parameters from the skull and scapula (25...
