.... To mimic conditions in the wild, we designed an experiment with captive, free-swimming harbor porpoises tasked with discriminating between two hydrophone-equipped targets and closing in on the selected target; this allowed us to gain insight into how porpoises adjust their acoustic gaze in a multi-target...

... hydrophones on the sound-producing nasal complexes of three echolocating porpoises ( Phocoena phocoena ) with symmetrical pairs of phonic lips. Using time of arrival differences on three hydrophones, we show that all recorded clicks from these three porpoises are produced by the right pair of phonic lips...

It was found that, in both species, the click sound production was coupled to a considerable...
