The embryology of cetaceans documents features that elucidate the interaction between
form and function in modern species, as well as their evolution from extinct ones. Prenatal …

Facial musculature in mammals underlies mastication and nonverbal communicative facial
displays. Our understanding of primate facial expression comes primarily from haplorrhines …

Hearing represents the major sense in harbour porpoises (Phocoena phocoena) and
impairment of hearing has a great impact on the survival of these animals. In this …

Pinnipeds are unique semiaquatic taxa possessing adaptations to hear efficiently both in

The morphology of the mammalian middle ear—including the size, shape, and stiffness of
individual ossicles—controls their vibrational response to sound and, is closely related to an …

Geometric morphometric studies of dolphins have traditionally concentrated on the skull,
while the mandible and its modularity have been little explored. We investigated the …

The present study, performed with a dual‐energy X‐ray (DXA) bone densitometer on a
series of fetal and newborn striped and short‐beaked common dolphins, shows that the …

Using the auditory evoked response technique, sensitivity to local acoustic stimulation of the
ventro-lateral head surface was investigated in a beluga whale (Delphinapterus leucas) …
