Investigations on Cetacea (1993)
Of the 79 recent species of cetaceans 51 have been examined relative to the osteology of the flipper and the scapula and, in addition to this, video-recordings of 13 different…
Observations on Pacific cetaceans of Californian and Mexican waters
Norris, K. S.; Prescott, J. H.
University of California Publications in Zoology (1961)
(...) For five years we have systematically gathered information of every available kind related to these animals. Fifteen species have been observed in sufficient detail to be considered here. These…
Observations of captive and wild cetaceans
Brown, David H.; Norris, Kenneth S.
Journal of Mammalogy (1956)
(...) During the first months of operation (March, 1954 to Sept. 1955) of the new oceanarium, Marineland of the Pacific, we have had numerous opportunities to observe the dolphins and…
Levels of organochlorine compounds, including PCDDS and PCDFS, in the blubber of cetaceans from the west coast of North America
Jarman, W. M.; Norstrom, R. J.; Muir, D. C. G.; Rosenberg, B.; Simon, M.; Baird, R. W.
Marine Pollution Bulletin (1996)
Levels of organochlorine compounds (PCDD, PCDF, PCB and organochlorine pesticides) were determined in cetaceans collected from the west coast of North America between 1986 and 1989. The samples included gray…
Emission of social sounds by marine animals
Au, W. W. L.; Hastings, M. C.
Principles of Marine Bioacoustics (2008)
(...) Sound emissions by odontocetes (toothed whales and dolphins) can be classified into two broad categories of frequency-varying continuous tonal sounds referred to as whistles and broadband clicks (Evans, 1967),…
Abundance and distribution of cetaceans in the Gulf of Alaska
Rone, Brenda K.; Zerbini, Alexandre N.; Douglas, Annie B.; Weller, David W.; Clapham, Phillip J.
Marine Biology (2017)
To effectively protect and manage marine mammals, contemporary information on their abundance and distribution is essential. Several factors influence present-day insight including the accessibility of the study area and the…
Comparison of dolphins’ body and brain measurements with four other groups of cetaceans reveals great diversity
Ridgway, Sam H.; Carlin, Kevin P.; Van Alstyne, Kaitlin R.; Hanson, Alicia C.; Tarpley, Raymond J.
Brain, Behavior and Evolution (2016)
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…

Reeves, R.; Notarbartolo di Sciara, G.
(2006)
(...) The Black Sea harbour porpoise, P. p. relicta, qualifies for listing as Endangered (EN) based on criteria A1d and A4c,d,e. The basis for inferences and suspicions leading to that…
Marine mammal sensory systems
Wartzok, D.; Ketten, D. R.

(...) 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…
Predation by killer whales (Orcinus orca) and the evolution of whistle loss and narrow-band high frequency clicks in odontocetes
Morisaka, T.; Connor, R. C.
Journal of Evolutionary Biology (2007)
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…
