What is the nervous system of a Cephalopod?
Cephalopods are widely regarded as the most intelligent of the invertebrates, and have well developed senses and large brains (larger than those of gastropods). The nervous system of cephalopods is the most complex of the invertebrates and cephalopods is the most complex of the invertebrates and their brain-to-body-mass ratio falls between that of warm- and cold-blooded vertebrates.The brain is protected in a cartilaginous cranium. The giant nerve fibers of the cephalopod mantle have been widely used as experimental material in neurophysiology for many years; their large diameter (due to lack of myelination) makes them relatively easy to study. Cephalopods are social creatures; when isolated from their own kind, they will take to shoaling with fish. Some cephalopods are able to fly through air for distances up to 50 m. While the organisms are not particularly aerodynamic, they achieve these rather impressive ranges by use of jet-propulsion; water continues to be expelled from the funnel while the organism is in flight.
