Dental Anomaly Causing Severe Maxillary Lesions in a Male Sowerby’s Beaked Whale (Mesoplodon bidens Sowerby, 1804)
Sowerby’s beaked whale (Mesoplodon bidens) is a poorly known cetacean species, and much of our current information comes from stranded animals. Herein, we describe a dental anomaly in an adult male stranded in 2019 in the Moray Firth, Scotland. The mandibular teeth (tusks) had erupted so their tips...
