Asked in Nervous System, Cephalopods
How are cephalopod nervous systems unique among mollusks?
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 nerve runs 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.
Asked in Starfish
How do sea star breathe?
Echinoderms move, feed and breathe with a unique water-vascular system ending in what are called tube feet. Sea stars use their tube feet to slowly pry open clams, mussels or other prey. Some sea stars can even evert their stomach between the two shells of a bivalve and digest the soft parts inside.
