A recent study suggests that the cold-blooded vertebrates are smarter and more sensitive than we think.  When we picture fish, it’s often in terms of our plates or aquarium tanks.

According to a new paper published in the journal Animal Cognition, fish socialize, use tools, develop long-term memories, enjoy back rubs, and can likely feel pain.
