I presume the question means the animal with the smallest brain as a proportion of its body weight. I found the following on http://faculty.washington.edu/chudler/news38.html
"Perhaps the distinction of the vertebrate (animal with a backbone) with the smallest brain is the deep sea fish called "Acanthonus armatus." This fish lives on the ocean floor at depths between 1,700 and 3,700 meters. A fish with a body weight of 140 g has a brain that weighs only 0.0035 g. On average, the brain of this fish makes up only 0.0247% of its total body weight."
