What amazing creatures! One of the coolest experiences I’ve lived scuba diving was an interaction with a cuttlefish. It would come towards me in its alien like swimming style and crazy eyes, while pulsating super cool colors, getting very close to my face and then quickly swimming back and forth and up and down, speeding up and slowing down, like performing some kind of ritual dance.
I think it was trying to hypnotize me, like Futurama’s good old Hypnotoad. What was the motivation behind, I will always wonder
The colors understanding is even more remarkable given that they are colorblind in the sense that they do not have different color cones, and likely rely on a very imperfect process of chromatic aberration that they can somehow translate back into color.
I spent 15 minutes watching a group of about 8 cuttlefish on a reef. There were clearly lots of complex group interactions going on between them. It is also amazing fast they can change colour.
