Lee A. Miller, “Prey Capture by Harbor Porpoises (Phocoena phocoena): A Comparison Between Echolocators in the Field and in Captivity”, J. Marine Acoust. Soc. Jpn., 37(3), 156-168 (2010).


Fig. 5

A harbor porpoise (Eigil) changing the shape of its melon during the production of a click train with high and low rates (inset below). (Video clip at 1/2 normal speed. The suction cups are EEG electrodes recording auditory evoked responses.)

Fig. 9

Video clip of a harbor porpoise capturing a (dead) fish. The video and sounds are at 1/10th normal speed. Note that echolocation continues after capturing the fish, unlike the case for insectivorous bats (see Figs. 1 and 13).
