How about octopuses?

I agree. Far more fits the "Alien" bill than a flipping (no pun intended) mammal.

I think the point of the article was that mammals are the closest thing to us that are still (almost) completely foreign.

If we can't talk to dolphins then how would we communicate with octopi? If not even octopi then how aliens?

I think that was more the point rather than trying to find the most alien intelligent animal to attempt to communicate with.
