The cephalopods have the most developed nervous systems. Cephalopods comprise squid, nautiluses, cuttlefish, and octopuses. One of their interesting features are eyes that are similar to vertebrates' eyes in their complexity.
A group of animals that has a spine is called vertebrates. This group includes mammals, birds, reptiles, amphibians, and fish. The spine, also known as the vertebral column, provides support and protection for the nervous system.
Animals are classified as vertebrates if they have a backbone or spinal column made of individual vertebrae. This group includes mammals, birds, reptiles, amphibians, and fish. Vertebrates typically exhibit bilateral symmetry and have a well-developed brain and nervous system.
A snake is a reptile. A snail is known as a mollusc.
I am not an expert on Octipi sharks are more my thing but i think that it is a cephalopod
Molluscs are invertebrates. They are such a diverse group of animals that it is difficult to generalise about the characteristics. They all have a mantle used for breathing. Their nervous system has a range of development with the most developed in the giant squid. Slugs, oysters, clams, snails are all molluscs. Most have a rasping tongue, most have a muscular foot, most have a type of "kidney" although it does not have the shape of a mammalian kidney.

No. The functional unit of the nervous system is the neuron. Neurons group together to form nerves.
