Young Humpback Lunge Feeding Outside Monterey Harbor

Our sunset departure aboard Sanctuary was met with rough, choppy conditions, but we did not have to travel far for our first encounter. Just outside the harbor mouth, a young humpback whale—one of three we would observe during the evening—was actively lunge feeding, breaking the surface to filter feed on schooling forage fish.

Lunge feeding is a highly energetic behavior typical of younger humpbacks capitalizing on rich coastal food sources. By accelerating rapidly from below, these whales engulf massive volumes of water and prey, utilizing their expandable throat pleats before using their baleen plates to strain out the water.

Pushing further out toward the deep waters of the Monterey Canyon, we encountered a highly active group of approximately 40 Pacific white-sided dolphins. They were traveling alongside a large aggregation of about 110 California sea lions, both species likely drawn to the same concentrated bait balls in the choppy seas, with winds holding out of the south at 11.7 knots.

Observing these multi-species feeding associations near the canyon edge is always a reminder of Monterey Bay's immense productivity. Even on rougher evenings, the convergence of deep canyon waters and coastal currents creates a highly reliable engine for marine life.
