Study Notes
Octopus Hunting Strategies
- Octopuses are intelligent cephalopods known for their problem-solving abilities, leadership in hunting groups, and diverse behaviours, such as using coconut shells for shelter and camouflage to evade predators.
- A study by the Max Planck Institute observed 13 hunting groups in the Red Sea, each comprising a large blue octopus (Octopus cyanea) and a group of fish.
- The octopus acts as the leader, directing the hunting group to potential prey.
Hunting Tactics
- Fish swarm around the octopus, suggesting potential prey locations, and the octopus directs the hunt by selecting the direction.
- Fish explore coral crevices, leading the octopus to prey by hovering near or moving between the crevice and the octopus.
- The octopus blocks the crevices to trap prey, and the fish consume any escaping prey.
- The octopus shows a preference for blue goatfish, likely due to their strong team hunting abilities.
- Blacktip groupers sometimes try to exploit the hunting group without actively hunting, and the octopus punishes these exploiters to maintain hunting efficiency.
- This hunting arrangement benefits both the octopus and the fish.
Benefits of Cooperation
- Fish gain access to prey hidden in crevices, unreachable by the octopus alone.
- Octopuses can effectively locate prey by following the fish's guidance, saving them the effort of searching independently.
Remaining Questions
- The study explores whether octopuses consistently partner with the same fish or if they randomly select partners.
- Researchers are investigating if octopuses choose skilled fish partners (e.g. Martha who is a good hunter, instead of Steve who is lazy).
- The study observed over 120 hours of underwater footage of these 13 different hunting groups.
