Journal of Experimental Biology (2010)
Echolocating toothed whales produce high-powered clicks by pneumatic actuation of phonic lips in their nasal complexes. All non-physeteroid toothed whales have two pairs of phonic lips allowing many of these…

Journal of Cetacean Research and Management (2010)
Iran has 1,700km of coastline that borders the Persian Gulf and the Arabian Sea in the northwest Indian Ocean. Apart from a handful of records, almost nothing is known about…
Click communication in harbour porpoises Phocoena phocoena
Clausen, K. T.; Wahlberg, M.; Beedholm, K.; Deruiter, S.; Madsen, P. T.
Bioacoustics (2010)
Sound plays an important role for toothed whales in foraging and communication. However, little is known about acoustic communication in the toothed whale species that only produce narrow band high…
Morphology and microanatomy of harbor porpoise (Phocoena phocoena) dorsal fin tubercles
Ginter, Carly C.; Böttger, S. Anne; Fish, Frank E.
Journal of Morphology (2010)
The unique pattern of small tubercles on the leading edge of the dorsal fins of harbor porpoises (Phocoena phocoena) has been widely noted in the literature, though their structure or…
Gas bubble disease in harbor porpoises (Phocoena phocoena) stranded in British Columbia
Raverty, Stephen A.; Spavin, Lisa; Cottrell, Paul; Ford, John; Hall, Anna; Gaydos, Joe; Haulena, Martin; Ivančić, Marina
Conference of the International Association for Aquatic Animal Medicine (2010)
Harbour porpoises (Phocoena phocoena) are among the most abundant small cetaceans in the northeastern Pacific and there is a distinct bimodal seasonal stranding trend. Increased numbers of animals present in…
Persistent organic pollutants and methoxylated PBDEs in harbour porpoises from the North Sea from 1990 until 2008: Young wildlife at risk?
Weijs, Liesbeth; van Elk, Cornelis; Das, Krishna; Blust, Ronny; Covaci, Adrian
Science of The Total Environment (2010)
In the European North Sea, harbour porpoises are top predators with relatively long life spans and a limited capacity for metabolic biotransformation of contaminants compared to some other marine mammal…
Paedomorphosis in two small species of toothed whales (Odontoceti): How and why?
Galatius, Anders
Biological Journal of the Linnean Society (2010)
To evaluate and assess the ontogenetic background for paedomorphosis in phocoenids, samples of 144 harbour porpoises, 81 white-beaked dolphins, and 130 Commerson's dolphins were compared in terms of the development…
Propagation of narrow-band-high-frequency clicks: Measured and modeled transmission loss of porpoise-like clicks in porpoise habitats
DeRuiter, Stacy L.; Hansen, Michael; Koopman, Heather N.; Westgate, Andrew J.; Tyack, Peter L.; Madsen, Peter T.
The Journal of the Acoustical Society of America (2010)
Estimating the range at which harbor porpoises can detect prey items and environmental objects is integral to understanding their biosonar. Understanding the ranges at which they can use echolocation to…

The effect of signal duration on the underwater detection thresholds of a harbor porpoise (Phocoena phocoena) for single frequency-modulated tonal signals between 0.25 and 160 kHz
Kastelein, Ronald A.; Hoek, Lean; de Jong, Christ A. F.; Wensveen, Paul J.
The Journal of the Acoustical Society of America (2010)
The underwater hearing sensitivity of a young male harbor porpoise for tonal signals of various signal durations was quantified by using a behavioral psychophysical technique. The animal was trained to…
