Well what I know about this question is that..............
Cephalopods nervous system is like this all echinoderms have a simple nervous system similar to that of a jellyfish. Around the mouth is a circle of nerve fibers called the nerve ring. In sea stars, a radial nerveruns from the nerve ring to the tip of each arm.The radial nerves control the movements of the sea star's arms.
One characteristic that is unique to echinoderms is the water vascular system. The water vascular system is a system of canals filled with fluid. It uses water pumps to help the animal move, eat, breathe, and sense its environment.The water vascular system of a sea star. Notice how water pressure from the system is used for many functions.
A nautilus is a cephalopod. It belongs to the class Cephalopoda, which also includes octopuses, squids, and cuttlefish. Unlike gastropods (snails and slugs) and bivalves (clams and oysters), cephalopods are characterized by their highly developed nervous systems and ability to exhibit complex behaviors. The nautilus is unique among living cephalopods for its coiled, chambered shell.
There are three main classes of mollusks: Gastropoda (snails and slugs), Bivalvia (clams, mussels, oysters), and Cephalopoda (octopuses, squids, nautiluses). Each class has unique characteristics and habitats.
Squids' and octopi's nervous system are the most advanced of all invertebrates
Cephalopods are considered the most advanced mollusks due to their complex nervous systems, highly developed brains, and sophisticated behaviors, which include problem-solving and social interaction. Their ability to rapidly change color and texture for communication and camouflage showcases advanced sensory processing and motor control. Additionally, cephalopods exhibit unique features such as jet propulsion for movement and specialized appendages that allow for intricate manipulation of their environment. This combination of traits sets them apart from other mollusks, highlighting their evolutionary success.
Answer 1A squid or an octopus.Answer 2A better answer for this question would be: They are an invertebrate in the phylum Mollusca meaning "soft bodied" (Mollusks). The class Cephalopoda means "head foot", meaning their arms and tentacles come from the head. All of their internal organs are cased in the soft section of the body called the mantle. There are actually 4 types of cephalopods: squids, octopuses, cuttlefish, and nautiluses. Each are unique in their own ways. For instance the nautilus is the only cephalopod that does not hunt. They are found in all oceans.
Snails are actually mollusks and crustacean. They are very unique creatures.
There are eleven main systems in the human body: circulatory, digestive, endocrine, immune, integumentary, lymphatic, muscular, nervous, reproductive, respiratory, and skeletal systems. Each system plays a unique role in maintaining the body's overall health and functioning.
== == The Movement Systems are the Muscular and Skeletal Systems. The Control Systems are the Dermal, Endocrine, Immune, Lymphatic, Nervous, Reproductive, and Sensory Systems. The Energy Systems are the Circulatory, Digestive, Excretory, Respiratory, and Urinary Systems. Source(s) My very smart brain.
The major systems of the body include the circulatory system, respiratory system, digestive system, nervous system, skeletal system, muscular system, endocrine system, immune system, and reproductive system. Each system plays a unique role in maintaining the overall health and function of the body.
I am not stealing anything but I want wikipedia to take all the credit (for their copyright) anyways this is the answer and read more on the link below for more information but this should explain "What is a cephalopod?", so here it is.They are an invertebrate in the phylum Mollusca meaning "soft bodied" (Mollusks).

Echinoderms are often considered regressive animals due to their unique evolutionary traits, such as their radial symmetry and a lack of centralized nervous systems, which contrast with the bilateral symmetry and more complex nervous systems seen in many other animal groups. Their larval forms are typically bilaterally symmetrical, but they undergo a metamorphosis that results in the adult form being radially symmetrical, suggesting a simplification in structure. Additionally, their reliance on water vascular systems for movement and feeding further illustrates a departure from more complex systems found in other phyla.
The 8 organ systems in the human body are the integumentary system, skeletal system, muscular system, nervous system, endocrine system, cardiovascular system, respiratory system, and digestive system. Each system plays a unique role in maintaining the body's overall function and health.
