She-ra Posted May 21, 2015 #1 Share Posted May 21, 2015 They are the masters of disguise. Not only can octopuses match color almost perfectly, they can also match texture, pattern and brightness of the object they try to mimic. We already know that their eyes display striking similarities to our own, but it turns out that the light-sensing abilities of these cephalopods doesn't end there.

They even learn by observation. Edited May 21, 2015 by Razer 1 Link to comment Share on other sites More sharing options...

I think you're right - they COULD take over the world Wow. They are so cool, my dad kept one as a pet in a small tank just a few feet away from a much larger tank with saltwater fish. That little guy did everything he could to escape and try to get into the larger tank with fish. Many times I had to pick him up off the floor as he was making his way to the other tank. He clearly knew what he was after. Edited May 21, 2015 by Razer 1 Link to comment Share on other sites More sharing options...

The only story I have to share is that I got *inked* once trying to get one back in the ocean. He got caught up in our boat like 4 feet off shore. Tried to get him off the boat and back in the water and he spewed. Ew. He was fine though we got him back int he water. 1 Link to comment Share on other sites More sharing options...
BeastieRunner Posted May 22, 2015 #6 Share Posted May 22, 2015 (edited) They also have sex by having the male insert his penis arm into the female's head (mantle). They are a crazy and magnificent creature! Edited May 22, 2015 by BeastieRunner 1 Link to comment Share on other sites More sharing options...
Zalmoxis Posted May 22, 2015 #7 Share Posted May 22, 2015 I wonder though how the octopus percieves the data from it's skin. It already has a set of eyes as shown in the illustration above. Maybe the skin data doesn't reach the consciousness part of the processing in the brain, only to react to the environment subconsciously. 2 Link to comment Share on other sites More sharing options...

The article theorizes that the systems are independent in case the octopus is distracted/unconscious/etc. and doesn't see a potential threat/change/etc. so the skin will still alter with camouflage to help it blend into its surroundings. The researchers managed to demonstrate that the camouflage was independent of the CNS and appeared to operate automatically. So it is more probable than not that the "skin sight" is subconscious. 1 Link to comment Share on other sites More sharing options...

Rhino666 Posted May 25, 2015 #10 Share Posted May 25, 2015 (edited) That's a damn good article. It makes you realise just how useless a human is if you take away all tools. Can't fly, limited swimming, gets lost, can't navigate well.etc etc Edited May 25, 2015 by Rhino666 1 Link to comment Share on other sites More sharing options...
