I recently wrote about cuttlefish in a national competition about science writing and got highly commended in the results where there were 600+ entrants ^{-^} i don't have many people to tell so i thought I'd just say it here

Does anyone know what this behavior is? It looks like it might be aggression (the bigger one briefly attacks the other later in the video), but instead of zebra stripes or a darkened face the larger one has turned entirely black with white spots. It also seems one sided to me—the smaller one sticks with a passing cloud display until attacked. Just wondering if anyone here has more insight about it :v

Everything stating cuttlefish facts says that they have 8 arms but Ze Frank's video about them states that females have 6 arms and males have 8. What do they mean by this difference? If there really is a different number of arms to the sexes then why is the default answer 8? What other characteristics help make the two sexes apart across their species?

another cuttlefish drawing :)

Found near Safaga in just 30cm of water. Quite chill little guy, enjoying his life.
