The dive response allows marine mammals to perform prolonged breath-hold dives to access rich marine prey resources. Via dynamic adjustments of peripheral vasoconstriction and bradycardia, oxygen consumption can be tailored…

The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis, YFP) is an endangered species endemic to the Yangtze River in China, and it is the only freshwater whale in the genus Neophocaena.…
Studies on odontocetes (e.g., porpoises) have revealed that these animals may adaptively use vision. The present study examined the contributions of vision to the approaching behavior of the harbor porpoise…
(...) 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…

The structure of the retina, the distribution of ganglion cells, and the extent of the tapetum lucidum were studied in Dall's porpoise (Phocoenoides dalli) with the aim of understanding the…
The refractive index of the cornea of a harbor porpoise eye was measured by two-wavelengths laser-interferometry. In the thickest part of the cornea a refractive index of about 1.53 was…
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…
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…
(...) Organization of the visual system in Cetacea still remains unclear in many respects. Of special interest are data on ganglion cell distribution in the retina. It is related closely…
