Echinoderms do not have a respiratory system similar to a person's. Instead, they have a water vascular (otherwise known as "ambulacral") system, made up of a network of canals to move water. This method accounts for the creature's gas exchange, feeding, and locomotion. Because of this characteristic, echinoderms lack gill slits.

What is an invertebrate with a system of fluid-filled tubes used to move and obtain food?
echinoderms
What do echinoderms use for movement?
Echinoderms, such as seastars and sea urchins, use their tube feet to move. Tube feet have suction discs which allows the echinoderm to crawl or stick to various surfaces.
What does the muscular system do in the human body?
The muscular system in the human body is responsible for movement, stability, and generating heat. It allows us to move our limbs, breathe, and maintain posture.
What is importance of muscular system?
allows you to move.
What is a closed system Apex?
A system that allows energy to move in and out but not mass.
What is the role in the circulatory system?
The role in the circulatory system is to pump blood throughout our body in order to breathe and to move.
Which of the following is NOT a characteristic of cnidarians?
Echinoderms generally have tube feet and are symmetrical radially. A feature they do not have is lungs to breathe air because they have a water based vascular system.
Do echinoderms have nerves?
Yes, the nerves help them feed and move.
Are echinoderms fast moving predators?
No, they move very slowly.
