Can octopuses hear?

If so, in what range?

I have an octo that I talk to all the time, but I have no idea if he can actually hear me or not.

Thanks in advance,
Shannen

No, they can't hear the way we do, but they can feel some vibrations - for instance, Carol (corw314) used to tap three times on the tank to signal her bimac and she got a response.

So by all means continue talking to your octopus - it means you're there at the tank trying to interact and that has a long term positive effect.

Just curious if voice pitch made any difference, since I'm usually making silly high-pitched noises. I know they are sensitive to vibration, we have hardwood floors, and he gets very still when he feels us walking on the floor.

Thanks for the info.

That would correspond to what others have reported - can't hear your voice, but can feel the vibrations on the floor.
