Today's interesting fact for the day has to do with the Octopus.

The octopus along with squid are considered to have the most complex brains in the mollusc phyla.

The octopus's brain seems to co-operate with neural ganglia in it's legs, the brain giving the leg ganglia general instructions and the leg ganglia determining how to do what the brain has asked, working more or less independently.

The alimentary canal (digestive tract) passes through the octopus's brain.
