Biology of Marine Mammals (1999)
(...) 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…

Two echolocation experiments are described. They were conducted on the same harbor porpoise housed in a sea pen, one year apart at Neeltje Jans, The Netherlands. The aims were to…
The ability of a finless porpoise (Neophocaena phocaenoides) to discriminate the material and size of a target by echolocation was investigated. The porpoise was required to choose a standard target…
The reported decline of the harbour porpoise in the coastal areas of the North Sea after 1940, has also been seen in Dutch waters. Information on the distribution and abundance…
A comparison of the acoustic waveforms of three different species, Phocoena phocoena, Phocoena sinus and Neophocaena phocaenoides of the sub-family Phocoeninae is made with the species Phocoenoides dalli of the…
The site and physiologic mechanism(s) responsible for the generation of odontocete biosonar signals have eluded investigators for decades. To address these issues we subjected postmortem toothed whale heads to interrogation…
Dall's porpoises, Phocoenoides dalli, were often incidentally caught in the Japanese salmon gillnet fishery in the North Pacific. In order to investigate the reasons for entanglement, their auditory characteristics and…
To reduce incidental catch of cetaceans in gillnets, two forms of acoustic modifications are reviewed here; one to make gillnets more reflective to cetacean sonar, and another using active sound…
The rate of occurrence of click trains of two harbor porpoises (Phocoena phocoena) were counted during 14 nights. We developed an echolocation signal detection system that was harnessed to a…
