Echolocation
Our sunset trip was amazing last night. We traveled around the south end of San Juan Island toward the Lime Kiln State Park. K-pod had been sighted near the light house. As soon as we arrived we were able to identify K-11.
We shut off our engine and put our hydrophone in the water. The next couple of minutes were astounding. K-pod was being particularly vocal. It is currently understood that orcas use echolocation for communication, navigation and hunting.
