According to Dr. Sampaio, what is the role of the octopus during a hunting expedition?
- To locate prey using its advanced sensory organs.

Study Notes
- Octopuses are intelligent marine animals known for using tools, camouflage, and now, leading hunting parties.
- A new study reveals octopuses' leadership role in hunting packs and their method of disciplining non-cooperative members.
- The research was conducted by scientists at Germany's Max Planck Institute of Animal Behavior.
Study Details
- Researchers, led by Dr. Eduardo Sampaio, analyzed over 120 hours of Red Sea underwater footage of 13 octopus-fish hunting groups.
- The hunting groups consisted of a big blue octopus (Octopus cyanea) and a group of fish.
- The fish seemed to suggest directions to the octopus while the group moved.
- The octopus would decide where to go and stop the fish from moving in other directions.
- Fish explored coral crevices, leading the octopus to potential prey by hovering or moving between the crevice and the octopus.
- The octopus would cover the crevice with its body to trap prey and grab it with an arm, with any escaping prey consumed by the waiting fish.
- The cephalopods teamed up with various fish species, especially favoring the blue goatfish due to its strong hunting abilities.
- Blacktip groupers sometimes tried to take prey without assisting, leading to the octopus "punching" them to drive them away.
- The octopus primarily punched the main exploiters, ambush predators that did not actively search for prey.
Findings
- The team published their findings in Nature on September 23, 2024.
- The hunting arrangement benefits both the octopus and the fish.
- Fish gain access to prey hidden in crevices that only the octopus can reach.
- Octopuses are able to follow the fish to food, saving the effort of searching alone.
Unanswered Questions
- Researchers are unsure whether octopuses team up with the same individual fish each time.
- It is unknown whether they simply partner with any blue goatfish they encounter.
