The harbor porpoise, and other toothed whales, use a biosonar click sequence that resembles the sequence of cries used by insectivorous bats when hunting for and capturing prey. The temporal…

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…
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…

Knowledge about harbour porpoise and bottlenose dolphin occurrence in Cardigan Bay Special Area of Conservation (SAC), Wales, is limited to daylight hours during summer, when conditions are suitable for traditional…

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…
Journal of Experimental Biology (2009)
Porpoise echolocation has been studied previously, mainly in target detection experiments using stationed animals and steel sphere targets, but little is known about the acoustic behaviour of free-swimming porpoises echolocating…

Dall’s porpoise (Phocoenoides dalli) echolocation clicks have not been widely recorded. Concurrent with visual observations, acoustic recordings of free‐ranging Dall’s porpoise were made offshore of southern California using a towed…
Aquatic Mammals (2009)
Finfish aquaculture is a prominent industry in the Bay of Fundy, Canada. The distribution of harbour porpoise (Phocoena phocoena) in the Bay during the summer and fall may be impacted…
Bioacoustics (2009)
Probably all odontocetes use echolocation for spatial orientation and detection of prey. We used a four hydrophone “Y” array to record the high frequency clicks from free-ranging White-beaked Dolphins Lagenorhynchus…
Anatomical Record (2009)
Toothed whales (Odontoceti, Cetacea) are the only aquatic mammals known to echolocate, and probably all of them are able to produce click sounds and to synthesize their echoes into a…
