Click communication in wild harbour porpoises (Phocoena phocoena) [PDF]
Scientific Reports, 2018 AbstractSocial delphinids employ a vocal repertoire of clicks for echolocation and whistles for communication. Conversely, the less social and acoustically cryptic harbour porpoises (Phocoena phocoena) only produce narrow-band high-frequency (NBHF) clicks with properties that appear poorly suited for communication. Nevertheless, these small odontocetes

Brucella ceti Infection in Harbor Porpoise (Phocoena phocoena)
Emerging Infectious Diseases, 2010 We describe Brucella sp. infection and associated lesions in a harbor porpoise (Phocoena phocoena) found on the coast of Belgium. The infection was diagnosed by immunohistochemistry, transmission electron microscopy, and bacteriology, and the organism ...

Range-dependent flexibility in the acoustic field of view of echolocating porpoises (Phocoena phocoena) [PDF]
eLife, 2015 Toothed whales use sonar to detect, locate, and track prey. They adjust emitted sound intensity, auditory sensitivity and click rate to target range, and terminate prey pursuits with high-repetition-rate, low-intensity buzzes.

Bite injuries of grey seals (Halichoerus grypus) on harbour porpoises (Phocoena phocoena). [PDF]
PLoS ONE, 2014 Bite-like skin lesions on harbour porpoises (Phocoena phocoena) have been suspected to be caused by grey seals (Halichoerus grypus), and a few field observations have been reported.

Time and tide: Seasonal, diel and tidal rhythms in Wadden Sea Harbour porpoises (Phocoena phocoena). [PDF]
PLoS ONE, 2019 Odontocetes have evolved a rich diversity of prey- and habitat-specific foraging strategies, which allows them to feed opportunistically on locally and temporally abundant prey.

Toothed whale auditory brainstem responses measured with a non-invasive, on-animal tag [PDF]
JASA Express Letters, 2021 Empirical measurements of odontocete hearing are limited to captive individuals, constituting a fraction of species across the suborder. Data from more species could be available if such measurements were collected from unrestrained animals in the wild ...

Marsvin Phocoena phocoena [PDF]
Bioacoustics, 2007 ABSTRACT 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 frequency (NBHF) clicks, such as the harbour porpoise Phocoena phocoena.
