What have eight legs, hunt among a group of fish and can throw a mean sucker punch?
According to research published in Ecology last week, the answer would be octopuses (yes, octopuses, not octopi—we asked).
Octopuses punch fish. Deliberately. Sometimes there's a reason, but other times, there's no discernible excuse. Researchers caught this behavior on video.
The first time researcher Eduardo Sampaio witnessed this phenomenon, he laughed. Normally that'd be fine but at the time he was underwater wearing scuba equipment.
"I almost choked on my regulator," he said in an interview with NPR's Morning Edition. "When I saw it for the first time, I just burst out laughing."
The octopus is typically a solitary creature, but sometimes an octopus might take part in a hunting party made up of fishes. A grouper's gestures, for example, can clue an octopus into the location of prey. Sampaio and his co-researchers were studying this mutually beneficial behavior when they came across an octopus punching fish while hunting.
