Yes, it's very simple.

Gills and a well developed nervous system
Echinoderms, such as starfish, have basal nerve ganglia that serve as a nervous system. They also have a water vascular system that acts as a circulatory system. They can reproduce, move, and digest food. Therefore, they are animals.
The name echinoderm means "spiny skin." Echinoderms have spines of various lengths that cover the outside of their bodies. Most echinoderms are supported and protected by an internal skeleton made up of bonelike plates. Echinoderms have a simple nervous system but don't have heads or brains.
Echinodermates possess a water vascular system.
The nervous system The central nervous system
No. Nervous System is comprised of the Central Nervous System (CNS) and the Peripheral Nervous System (PNS) The PNS is comprised of the Somatic Nervous System and the Autonomic Nervous System The Autonomic Nervous System is comprised of the Sympathetic Nervous System, the Parasympathetic Nervous System and the Enteric Nervous System
water vascular system
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.
yes they do
