Despite their reputation as loners, it turns out octopuses will happily hunt in groups with other species as long as everyone knows who's boss.
Scientists in Germany have captured hours of footage of octopuses working in tandem with different species of reef fish to track down prey like smaller crustaceans, fish and molluscs and flush them out of their hidey-holes.
These hunting groups follow "a very complex leadership dynamic" that's not so different from your average human workplace, says biologist Eduardo Sampaio.
"Say there are three or four that are pitching ideas or providing options. So these are the fish," Sampaio told As It Happens host Nil Köksal.
