Again, no, they don't have a brain. The central ganglion has a bulb behind the lobster's eyes that principally houses the nerve bundles that handle vision. The processes that make up this section of the central ganglion account for 60% of the weight of the central ganglion. In other words, what gets mistaken for a 'brain" is the optic nerves! Incidentally, there are no receptors that can handle much beyond vision cues. I know. I looked for them. For 2 years.
Also, the Lobster Institute is made up of scientists, not marketing people or lobstermen.
I stand corrected, my original statement was based on knowledge collected from a biology class 15 years ago. I just did some googling and learned about how autonomous the ganglion are in lobsters. What surprises me is that there is a lot of literature and diagrams on the net that still refer to the central ganglion as a brain. The anatomists, biologists and zoologists need to get together and get the definitions straight on what a brain really is.
