Anyone know what their predators and if possible a source where you found this out. thanks!

What an interesting question. Of course I did a google search on "Octopus macropus" + predators and found a ton of references there. However, the greatest majority allude to the colour pattern of macropus having something to do with predator avoidance .... but none (that's not to say nothing exists) actually detailed these predators.

Goes to show the limitations of google and/or science.

Chejjjj(+1), I suggest you do the same google search; I am afraid that you might have to wade through quite a bit before you find what you are looking for.

Although if you click here (http://www.icm.csic.es/scimar/PDFs/sm70n3407.pdf) you'll find Risso's dolphin eating this species.

Ya i did the google search as well, but like you said much comes up as predator avoidance... oh well back to searching

interesting, Cephbase (http://www.cephbase.utmb.edu/) only has a prey listing, no predator listing....

What about moray eels? They don't seem to figure in the Predator Base of CephBase, though.
