What invertebrate is most intelligent?
Of all invertebrates, octopuses are thought to be the smartest. They can be trained to do all kinds of stuff, and they figure stuff out on their own as well. One octopus in a zoo was observed squirting water at the lights on the ceiling and causing them to short-circuit, all because it was bored. It stopped this as it was given toys to entertain it. They're also the only invertebrates to use tools - some species use coconut shells to build themselves a home, carrying them for long distances to use them later on. This signifies a bit of thinking that's not common in invertebrates.
On land, the most intelligent invertebrate is thought to be the Portia jumping spider, which plucks at the webs of other spiders in intricate patterns to make them think there's prey or a mate and approach, and then it attacks them. It can learn lots of individual patterns associated with species of prey, and even improvise based on what it's learned.
