Wow, I am actually surprised that squids are in the top 25 of the smartest animals on earth. This is a very interesting fact. I see squids every day, as I really love fishing, and I used to hook a squid for bait. It's a very good bait, you can catch very nice fish on it. However, there are different ways of hooking it, depending on what type of fish you are willing to catch. I have read a lot of information about squids used as a bait, but I didn't know that they are so smart. Thank you for sharing this article, it's very interesting and useful!
