Octopus

In the American Museum of Natural History, in the Hall of Biodiversity, there is a giant model of an octopus hanging from the ceiling. Initially, I was not that motivated to read about octopuses, however I became drawn into this article about them and was quite amazed. Apparently they are the one of the most intelligent of the invertebrates, with the intelligence of a house cat. Occasionally kept as pets, they have been known to escape from secure aquariums and break into other ones in search of food, due to their problem solving ability. They have even been able to open jars once they have learned from observation. They also have 3 hearts, so along with eight arms and their intelligence, it probably makes them better than many people we know :)
