Investigations on Cetacea (1970)
The forced choice variation of the method of constant stimuli was used to study the ability of angular discrimination at 2 kHz of a harbour porpoise Phocoena phocoena. A minimum…

The olfactory system of the harbour porpoise is reduced but has a function. The visual system of the harbour porpoise is badly developed, and its inferior to the one of…
The inner ear anatomy of cetaceans, now more readily accessible by means of nondestructive high-resolution X-ray computed tomographic (CT) scanning, provides a window into their acoustic abilities and ecological preferences.…
Hearing sensitivity, during trials in which a warning sound preceding a loud sound, was investigated in two harbor porpoises (Phocoena phocoena). Sensitivity was measured using pip-train test stimuli and auditory…

Anthropogenic sound in the marine environment can have negative consequences for marine fauna. Since most sound sources are intermittent or continuous, estimating how many individuals are exposed over time remains…
Airguns used in seismic surveys are among the most prevalent and powerful anthropogenic noise sources in marine habitats. They are designed to produce most energy below 100 Hz, but the…
Hearing is one of the major senses in whales and dolphins (cetaceans). This is the first report of severe mycotic otitis media in a cetacean, a juvenile female harbour porpoise…
Hearing is the primary sensory modality for toothed whales, but it is not known at which age it is fully developed. For newborn calves, hearing could fill an important function…
(...) In this chapter, we discuss marine mammal audition, vision, chemoreception, tactile sensation, and magnetic detection. We begin with an overview of the basic aspects of sensory receptor systems, and…
