1. Herding and Driving:
* Dolphins work together to herd fish into a tight school, using their bodies to create a "net" of bubbles or sound waves. This makes it easier for the dolphins to catch their prey.
* They may also drive fish towards shallow water or towards other dolphins waiting to ambush them.
2. Wave-Washing:
* Some species, like the bottlenose dolphin, will create waves with their bodies to dislodge fish from the seabed or coral reefs. This technique is particularly effective in shallow waters.
3. Sound and Communication:
* Dolphins use echolocation to locate and track prey. They emit high-pitched clicks and whistles that bounce off objects, allowing them to "see" their surroundings even in murky water.
* They also use complex vocalizations to coordinate their movements and communicate with each other during hunts.
4. Ambushing and Cornering:
* Dolphins will often ambush their prey from below or behind, surprising them and making it easier to catch them.
* They may also corner fish against a rocky outcrop or a reef, preventing them from escaping.
5. Team Roles:
* Some species, like the bottlenose dolphin, will even have specific roles within a hunting group. For example, some individuals may be responsible for herding the fish, while others focus on the final capture.
The benefits of cooperative hunting for dolphins:
* Increased success rate: Working together makes it much easier for dolphins to catch their prey.
* Efficiency: Cooperative hunting allows dolphins to cover more ground and exploit a wider variety of prey.
* Flexibility: Different hunting strategies can be employed depending on the prey and the environment.
Dolphins are truly masters of cooperative hunting, showcasing their incredible intelligence and teamwork skills.
