Views: 1707 | Duration: 205
Alaskan boat company Ketchikan Charters managed to capture the high-pitched conversation between killer whales during an outing in Ketchikan on October 1. Using a hydrophone (a microphone used for underwater recordings), Ketchikan Charters managed to amplify the sounds of the whales’ animated conversations as they darted in and out of the water.
