A case report of supernumerary maxillary canines in a male Sulawesi babirusa (Babyrousa celebensis).

Male Sulawesi babirusas (Babyrousa celebensis) are known for their distinctive backward-curving canine tusks. Previous research on the anomalies of canines in male babirusa skulls has demonstrated a high prevalence of growth abnormalities due to failure in the rotation of the alveolar process and the curvature of the canines, while the numerical abnormalities were found to be rare. This study focused on supernumerary maxillary canines as observed in a wild-caught babirusa in an ex situ conservation program. This report represents the first publication of photographic evidence of a living babirusa with three right maxillary canines, one left maxillary canine growing toward the right side of the snout, and two overgrown mandibular canines threatening to erode the forehead.
