YouTube description: "Octopuses appear to deliberately throw debris, sometimes directed at other octopuses, according to a study published November 9, 2022 in the open-access journal PLOS ONE."

Darren Incorvaia, in a New York Times story published that same day, offered an entertaining perspective on the scientists' findings as well as commentary by octopus authorities not involved in the work.
