On our approach to Monterey Bay, we came across a pod of humpback whales in what appeared to be a feeding frenzy. Three whales (two adults and one baby) circled our boat as we all sat mesmerized. They moved fast, pushing a lot of water, swimming in ways we'd not seen. They would roll over on their sides and open their mouths allowing their throat grooves to expand like an accordian, collecting a ton of water that they would then push back through their baleen to filter. They stayed near the surface and were active, moving around our boat through several rotations, like they were corralling us. Windy remarked how graceful and tranquil they seemed. It was almost like a water ballet as the three of them were often synchronized. They came very close to us and we repeatedly urged the girls (and ourselves) to hang on to something, concerned we'd get bumped and jostled by one of these animals. But we soon relaxed and enjoyed the half-hour show. When they finally sounded, we continued on to our anchorage, excitedly describing to each other what we'd seen.
