The narrow‐ridged finless porpoise Neophocaena asiaeorientalis is a small‐toothed whale with a coastal habitat and is sensitive to human activity. Aerial sighting surveys were conducted in 2012 to evaluate the…

This short communication reports an observation of unusual non-agonistic interactions between a juvenile harbour porpoise (Phocoena phocoena) and a group of bottlenose dolphins (Tursiops truncatus) in the Marmara Sea on…
The highly lipid-rich blubber in the hypodermis is a specialized structure that functions in thermoregulation, energy storage, buoyancy control, locomotion, and streamlining the body shape in marine mammals. The key…
...This short note documents instances of prey handling and consumption of large fish species along the West Coast of the United States (U.S.), including the Salish Sea (inland waters of…
Social group dynamics are known to impact odontocetes’ health and welfare in captivity. Social dominance and agonistic interactions that occur to establish and maintain these relationships might express themselves differently…
Temporary hearing threshold shift (TTS) caused by fatiguing sounds in the 1.5 to 16 kHz range has been documented in harbor porpoises (Phocoena phocoena). To assess impacts of anthropogenic noise…
If harbor porpoises (Phocoena phocoena) are impaired in their foraging ability because they need to move away from anthropogenic sound sources, their fitness may be reduced. Understanding how much harbor…
Naval sonar systems produce signals that may affect the behavior of harbor porpoises (Phocoena phocoena), and behavioral responses may be influenced by the received signal and by the signal-to-noise ratio…
Naval sonar signals may affect the behavior of harbor porpoises (Phocoena phocoena). The 53C sonar system produces 1,600 ms sonar signals in the 3.5 to 4.1 kHz band, each consisting…
Seasonal changes in food consumption, respiration rate, and body condition in a healthy captive male harbor porpoise (Phocoena phocoena) from the North Sea were recorded over 8 y. He was…
