Cooperative hunting is a strategy where two or more animals work together to find, chase, and capture prey they would struggle to catch alone. It goes beyond simply being in the same place at the same time. True cooperative hunting requires individuals to respond to each other’s movements, time their actions, and sometimes take on entirely different roles during a hunt. This behavior appears across a surprising range of species, from wolves and orcas to spiders and even fish.
What Makes It Different From Group Hunting
Not every group of animals hunting in the same area is cooperating. Scientists distinguish between levels of complexity. At the simplest level, animals may hunt near one another and benefit from sheer numbers without actually coordinating. African wild dogs, for example, sometimes gain an advantage simply because more dogs chasing multiple prey means more total catches, a pattern researchers describe as “additive opportunistic capture.” Each dog is essentially hunting for itself, and the group benefit is a statistical byproduct.
True cooperation begins at the level of coordination, where multiple individuals target the same prey and adjust their positions relative to each other in real time. They chase together through direction changes, follow similar trajectories, and may encircle a target as a unified group. The highest level is collaboration, where individuals take on distinct, complementary roles during a single hunt. One animal drives prey while another blocks an escape route, or one flushes a target while others wait in ambush. This role differentiation is the hallmark of the most sophisticated cooperative hunters.
Chimpanzees and Role-Based Hunting
One of the clearest examples of role-based cooperation comes from chimpanzees hunting red colobus monkeys in forest canopies. The youngest and least experienced chimpanzee typically acts as the driver, climbing into a tree to force the monkeys to flee. Off to the side, three other chimpanzees serve as blockers, running ahead and climbing trees to funnel the monkeys into a narrowing path. As the prey moves, the blockers adjust their positions to reform the trap. The final role belongs to the ambusher, usually the most experienced individual, who anticipates the monkeys’ escape route and waits hidden among the leaves. When the colobus monkeys flee toward what seems like an opening, the ambusher emerges to make the catch.
This kind of hunting demands that each participant understand not just where the prey is, but where the other hunters are and what they’re doing. It suggests a level of spatial awareness and anticipation that goes well beyond simple chasing.
Orcas and the Wave Wash
Orcas have developed one of the most physically impressive cooperative techniques in the animal kingdom. When a seal is resting on an ice floe, a group of orcas will first break a large floe into smaller, less stable pieces. Then they swim together in a synchronized charge toward the floe, generating a powerful surface wave that washes over the ice and slides the seal into the water. The entire maneuver requires only a few seconds of sudden acceleration, but the coordination behind it, timing the approach so all individuals contribute to the same wave, reflects precise group timing.
Some orca populations also tilt ice floes to dump prey into the water. These tactics are culturally transmitted, meaning young orcas learn them from older family members rather than figuring them out independently.
Harris’s Hawks and Relay Hunting
Harris’s hawks are one of the only raptors that hunt cooperatively, and they use at least two distinct group tactics. In relay hunting, birds take turns chasing prey. One hawk pursues the target, then peels off as another takes over, then another, cycling until the prey is too exhausted to run. In the flush-and-ambush approach, several hawks surround the hiding spot of a rabbit or similar prey. One bird dives in to flush the animal out while the others wait, positioned and ready to pounce. These hawks live in family groups of up to seven, and their cooperative strategies allow them to catch prey that a single bird would almost certainly lose.
Cooperation Between Different Species
Cooperative hunting doesn’t always involve members of the same species. In the Red Sea, coral groupers actively recruit giant moray eels for joint hunts. When a grouper spots prey hiding in a crevice it can’t reach, it swims to a resting moray eel and performs a rapid head-shaking signal directly in front of the eel’s face, shaking three to six times per second while raising its dorsal fin. If the moray follows, the grouper leads it to the hiding spot and sometimes performs a headstand above the crevice, shaking its head to indicate the precise location. The moray can slither into gaps the grouper cannot, flushing prey out into open water where the grouper is waiting. Both species benefit, though not necessarily from the same individual prey item.
This is remarkable because the grouper is using a specific visual signal to communicate intent to a completely different species, a behavior that was once assumed to require a level of cognition found only in mammals.
Even Spiders Do It
Social spiders in the genus Stegodyphus build communal webs and attack prey collectively. When vibrations travel through the shared web, multiple spiders respond and converge on the source. Research has shown that groups remaining physically close together on the web attack significantly faster than groups spread apart. Colonies where spiders interact more frequently before a prey encounter also respond at higher speeds. This cohesion matters because social spiders can subdue insects much larger than any individual could handle alone, and faster response times translate directly into higher capture success.
Why Cooperation Pays Off
The most obvious advantage is a higher success rate. African wild dogs succeed on 60 to 90 percent of their hunts, compared to roughly 25 percent for lions and 55 percent for cheetahs. That efficiency is critical for animals that burn enormous energy during long chases.
Cooperative hunting also opens up prey that would otherwise be inaccessible. A single wolf cannot bring down a moose. A lone orca cannot wash a seal off an ice floe. A solitary chimpanzee rarely catches a colobus monkey in a forest canopy with dozens of escape routes. Group coordination closes those escape routes and creates opportunities no individual could generate alone.
The cost is that food must be shared. Whether each individual ends up with more calories than it would get hunting solo depends on group size, prey size, and how evenly the food is divided. In African wild dogs, per capita energy intake varies with pack size, and there appears to be an optimal group size beyond which adding more hunters doesn’t improve each individual’s share.
The Cognitive Demands
Simple cooperative hunting, like a group of fish herding a bait ball, requires relatively modest brainpower. Each individual follows basic rules: stay near the group, move toward the prey. But the kind of role-based collaboration seen in chimpanzees or the signal-based recruitment used by groupers demands much more. Animals must track the positions and likely actions of both prey and hunting partners simultaneously. They need to anticipate where prey will go, not just where it is now.
In humans, cooperative hunting may have been a major driver of cognitive evolution. Researchers have proposed that shared intentionality, the motivation and ability to align mental states with others and pursue a common goal, was favored in early Homo erectus partly to support persistence hunting, where groups chased large prey over long distances until it collapsed from exhaustion. Archaeological evidence from southern South America shows that humans were hunting megafauna extensively before 11,600 years ago, with specialized projectile point technology emerging around 12,900 years ago that appears linked to the rapid collapse of large animal populations. That kind of organized, large-scale hunting required planning, communication, and shared goals that may have pushed human cognition in directions no other species has followed.
