Remotely-deployable non-invasive (suction-cup attached) tags to record underwater behavior of cetaceans have recently been developed. How useful these tags are for applications on a broad range of species has yet…
A series of behavioural surveys were conducted in Hong Kong upon resident populations of Indo-Pacific hump-backed dolphins (Sousa chinensis) and finless porpoises (Neophocaena phocaenoides). The surveys were carried out from…
Most harbour porpoises found dead on the north–east coast of Scotland show signs of attack by sympatric bottlenose dolphins, but the reason(s) for these violent interactions remains unclear. Post–mortem examinations…
