Here, we present an overview of active-sensing systems used by weakly electric fish, bats and odontocetes, and consider...

... et al., 2012) . Odontocetes may be vocally active for reasons other than keeping the group together ( Taruski, 1979 ; Weilgart and Whitehead, 1990 ; Zwamborn and Whitehead, 2016 ) and not necessarily for the purpose of homing by sound for foraging group members. However, the temporal patterns...

... threshold of the porpoise differed significantly from those for other frequencies. At the lowest test level (SnL=18 dB) the median was 522 ms. This value was expected to be much closer to the hearing threshold level, especially for a small odontocete like the harbour porpoise ( Blackwood, 2003 ). Click...
