The video of octopuses punching fish is quite surprising and funny to me. I know animals display certain odd behaviors from time to time, but seeing an octopus sucker punch a fish is very amusing. What are the octopuses thinking when they do that? Is it a reflex reaction or was it intentional? Furthermore, what did the fish do to provoke the ire of the octopus? A paper suggests that the reason for this is that certain fish are taking advantage of the octopus on a hunt, and the octopus is merely retaliating.
On another note, Marina Wang from Hakai Magazine had created a comic based on a new study where researchers looked into the biomechanics of the octopus punch. Take a look at the comic here.
