Octopuses are strange creatures, with three hearts, eight arms and a nervous system distinct from any other animal. These fiercely intelligent creatures are jam-packed with over 500 million neurons, but over two thirds of these neurons are located within their arms and body. Many scientists therefore think that octopuses' arms act independently from the brain, but a new study suggests that an octopus' arms and brain are more connected than previously thought.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/XpxXeKXMSPY
