Orcas can generate waves up to a meter high just by swimming in unison toward an ice floe.
Orcas, or killer whales, use a technique called wave-washing to hunt seals resting on ice floes. By synchronizing as a pod, they generate a wave large enough to sweep seals into the water, where the whales can attack. This method requires precise timing and coordination, demonstrating advanced group hunting tactics. Pods will circle the floe, position themselves at the right angle, and then simultaneously surge forward to dislodge the prey. Seals often underestimate the intelligence and planning involved, assuming the water is safe. Wave-washing is taught across generations, with younger orcas observing and participating under guidance. This strategy allows orcas to hunt efficiently without direct chase, conserving energy while increasing success rates. Environmental factors such as ice thickness and wind direction are subtly accounted for in the planning. It’s a rare example of tool-like manipulation in marine hunting.

Wave-washing highlights the cognitive sophistication of orcas, showing they can plan and execute complex coordinated attacks. It demonstrates that predator intelligence can extend beyond brute strength or speed into environmental manipulation. Young whales learn observationally, ensuring that this technique persists across generations. Such hunting strategies give orcas an evolutionary edge in icy habitats where direct pursuit is difficult. The behavior also reinforces social cohesion, as coordination and timing are critical for success. Pod members communicate and adjust in real-time, showcasing emergent problem-solving abilities. Wave-washing exemplifies how apex predators innovate rather than simply overpower their prey.
Changes in sea ice patterns due to climate change could alter orcas’ ability to employ wave-washing effectively. Understanding this behavior informs conservation efforts and helps predict ecosystem impacts if ice-dependent prey populations decline. Studying orca wave-washing provides insight into complex predator-prey dynamics and marine intelligence. It challenges assumptions that large predators rely solely on speed and force, highlighting strategy, observation, and teamwork. Environmental manipulation becomes a key hunting tool rather than just a natural byproduct. Wave-washing also shows the critical interplay between physical habitat and behavioral adaptation. Protecting ice-rich hunting grounds ensures that these intricate behaviors persist for future generations.
