Description
Summary:Adult male Pacific walrus Sivuqaq demonstrating underwater clapping behaviour video filmed at normal speed in front of the pool's glass window. Black and white numbers indicate distance (m) to the receiving hydrophone. ;High-speed video (recorded at 1 frame/ms) of adult male Pacific walrus Sivuqaq performing a single underwater clap. The film shows formation and collapse of the cavitation bubbles and the duration of the acoustic impulse (shown by the trigger of the LED indicator in upper left corner). The first video is shown at 30 frames per second, the second video is the same sequence shown at 15 frames per second. These MOV files are compressed from the original recordings.
