Ken Norris first described a potential mandibular sound reception pathway in odontocetes in 1964. To date, sound reception paths in mysticetes remain unknown. To understand hearing mechanisms in baleen whales, a thorough examination of their auditory anatomy is required. This study combines classical dissection with biomed1cal imaging techniques such as X-ray, computerized tomography (CT), and magnetic resonance imaging (MRl) to describe the anatomy of the minke whale head with a focus on the ear region. Six individuals have been examined to date.
