Do octopus have brains
Octopuses have an extensive nervous system, with over 500 million neurons, similar in number to that of a dog.

Number of Brains: 9. The octopus has 9 brains, one for each tentacle and one at the head. The main brain resides at the head while the other brains are interconnected as fused ganglia, with each brain having its own set of neurons. With more than 500 million neurons, only 30 percent of them are located at its main brain. Octopus Brain Structure.

Octopuses can change the texture and appearance of these papillae whenever the situation so demands and are able to get out of sticky situations.
What the team found was that octopuses have a lot of microRNA, or miRNA. They found 164 miRNA genes grouped into 138 miRNA families in the common octopus, and 162 miRNA genes grouped into the same 138 families in the California two-spot octopus. And 42 of the families were new, mostly in the brain and neural tissue. One of the really neat things about cephalopods is that even though they have a centralized brain, they also have a highly distributed nervous system. Lots of processing, even “thinking,†can happen throughout the body. Octopus arms can control much of their own movement, and the body of the squid may be able to control itself.
