A group of humpback whales were filmed lunge feeding near Monterey Harbor in California on July 26. Chere Tamura filmed the event while out on a whale-watching trip with Monterey Bay Whale Watch.

Nancy Black, who operates Monterey Bay Whale Watch/Gowhales.com, told Storyful that the footage shows the group of 10 whales cooperatively lunge feeding on anchovies. The practice allows the whales to catch more food than feeding alone and requires communication and very coordinated behavior, Black said. Credit: Monterey Bay Whale Watch/Gowhales.com via Storyful
