And how do we know that the squid can do all this?
Because we took the time to stop and study them. So, why would other life forms not study us, again? How does this analogy work?
How do we know? Because we put them in a controlled environment and isolated each variable until only one remained. There was no need to travel any inconvenient distance to find one or to study them. You either ordered them from a biological supply house or trawled some up. Not particularly exciting. Even spatial or temporal studies of the communicative properties would be more feasible in an in situ lab environ rather than a field study. Field studies are generally much more expensive than a lab study.
You missed the point again here though. We see that they can communicate with each other. We see convergent evolution in the structure of their optical systems and that's real nice for us, a species still discovering the other species on the planet we inhabit. Proximity to the study subject is the major factor.
Squid understand other squid species within their limited visual vocabulary. We, the advanced species that has sent scientific instruments to the end of the heliosphere, cannot exhibit any warning or threatening signs to a Humboldt to prevent it from attacking us as scuba divers.
An advanced species sees and understands the communicative properties, but yet cannot communicate back.
Take it to another analogy. We can communicate in a limited fashion with a very select set of very intelligent individuals in a few primate species. Yet we cannot communicate our desire to the chimp to not take a crap on the floor.
Another factor that I didn't think to mention and the squid reminded me, is the "cute" factor. The first time I walked through the ATM-Galveston wet lab that housed the cephalapods, they had a section in a corner with the nautili by themselves. The grad student or PhD that gave us the tour mentioned that they were kept out of the way because most of the staff didn't like looking at them. Their eyes are spooky in person. Trained biologists and behaviorists, yet they didn't want to look at that species so they stuck it in the corner.
Similarly, the cape hunting dogs of Africa have exceptionally complex and robust social interaction and hunting patterns. Seen a lot of them on Nat Geo? Nope, because they're ugly as hell.
It seems a laughable concept, but an alien species might find stinking, pasty, flacid bags of leaking liquid wrapped around a calcium endoskeletal system that requires exchange of potentially diseased fluids to reproduce; repulsive to an extreme.
As was mentioned by another post, from a macroscopic view we are no more interesting than a virus that has learned to manipulate it's environment to a limited degree. A virus cannot reproduce without an inclusion of foreign nucleic acid material, and neither can a human female.
