Masculinization? Rare variation in canine length among female water deer (Hydropotes inermis) can lead to errors in sex identification

Most cervids feature antlers for mate competition, but water deer possess uniquely elongated maxillary canines instead. This study examined the presence of elongated canines, a trait usually seen in males, in female water deer from 185 individuals culled in South Korea. Measurements of body length,...

Description
Summary:Most cervids feature antlers for mate competition, but water deer possess uniquely elongated maxillary canines instead. This study examined the presence of elongated canines, a trait usually seen in males, in female water deer from 185 individuals culled in South Korea. Measurements of body length, height, and mass were recorded, along with assessments of reproductive capability. The results showed that 1.6 % of the females exhibited elongated canines, retaining their fertility. Their body sizes remained within the typical range for their same age group, with their canines continuing to grow for at least three years. Thus, this rare variation, which is similar to males, may lead to infrequent errors in sex identification based on physical appearance.
