Are fish smart? What do you think? Let's research it! I am reading a book called "Eating Animals" by Jonathan Safran Foyer, I am not that far into it but it is about, well.....eating animals. I just got to the part where it talks about how fish may actually be smart. It is said that fish may have the mental capacities of non-human primates. What can you find out? Comment below to share your findings! Here are some fish playing chess. Enjoy!
