- Biologist Eduardo Sampaio from the University of Lisbon in Portugal: "Octopuses and fishes are known to hunt together, taking advantage of the other's morphology and hunting strategy... Since multiple partners join, this creates a complex network where investment and pay-off can be unbalanced, giving rise to partner control mechanisms." Original paper: "Octopuses punch fishes during collaborative interspecific hunting events" -- "Here we report a series of events ... where different Octopus cyanea individuals engage in active displacement of partner fish during collaborative hunting."
