Sensory Abilities of Cetaceans (1990)
(...) Watkins et al. (1977) and Dudok van Heel (1981) point to similarity in sound output in Cephalorhynchus and Phocoena, and suggest that it may be the result of convergent…

(...) 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…
We compared mature dolphins with 4 other groupings of mature cetaceans. With a large data set, we found great brain diversity among 5 different taxonomic groupings. The dolphins in our…
Lactation plays a vital role in reproductive success, evolving with ecological adaptations of mammalian life histories. Knowledge of the lactation process in odontocetes is scarce and limited to a handful…
The effects of tagging on small cetaceans are difficult to assess due to logistical difficulties in recapturing the whales. In this study two narwhals, Monodon monoceros, and five harbor porpoises,…
Concentrations of thirty two polychlorinated biphenyls (PCBs) were determined in the blubber of five sympatric species of odontocetes stranded or by-caught along the Northwest coast of the Iberian Peninsula: common…
The blubber thicknesses of 5 male and one female harbour porpoises were measured ultrasonically in 9 positions on the body over various periods of time. Most animals were immature and…
(...) 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…
A disparate selection of toothed whales (Odontoceti) share striking features of their acoustic repertoires including the absence of whistles and high frequency but weak (low peak-to-peak source level) clicks that…
Complex foldings of the vaginal wall are unique to some cetaceans and artiodactyls and are of unknown function(s). The patterns of vaginal length and cumulative vaginal fold length were assessed…
