What adaptations would limit an Octopus's survival if it were moved to a different zone?

Question

I have a science project and could not figure this one out. I'm not doing a certain species of octopus, just a plain general octopus. I have to provide three examples why it could not live in a different zone. Also, does anyone know what method of census taking and/or observation would be best to monitor an octopus? I have to tell three ways this information in used.
