How humpback whales hunt down tiny fish

Humpback whales use stealth and deception to hunt small fish, employing a technique called lunge feeding. A study from Stanford University reveals that whales open their mouths at precise moments to avoid triggering an escape response in fish. This method allows them to capture a significant portion of a fish school by expanding their jaws to engulf water and fish, then filtering out the water before swallowing the fish.
