At first I did not id the sponge as a sponge and was afraid it was a frog fish or some other creature that was going to eat the cuttle like the last film you made use watch (and continues to crop up ).
Interesting coloration, how did you id the cuttle?
I just read the comments... although I am questioning that ID - it may be Sepia mestus, but as always, cephalopods are difficult to ID from photos/videos alone...
