Crayfish breathe using gills, which are located between the carapace (the exoskeleton of the cephalothorax) and the lateral body wall, in the branchial chamber.
Oxygen and carbon dioxide are exchanged between the blood and water across the gill surface as water is circulated through the branchial chamber by the beating of the gill bailer on the second maxilla.
Starfish (Phylum Echinoderm) obtain oxygen through their tubefeet and the bumps on their skin. The tubes in the bumps and the feet take in the oxygen and pass it along to the tissue. From there it goes back out into the sea water as Carbon Dioxide.
Gas exchange in sea stars (starfish) occurs over their surface: they have neither gills nor lungs. Folds of skin on their dorsal surface permit gas exchange, as do the tube feet on their ventral surface. Also, they have a water-based vascular system, which also performs gas exchange.
jellyfish comes under phylum CELENTERATA in class SCYPHOZOA . JELLY FISH DOESNT REQUIRE RESPIRATORY ORGAN AND BREATHES THROUGH THEIR THIN SKIN

What is attached to crayfish organs that keep them all together?
Crayfish have a connective tissue called the mesentery that attaches organs to their body wall, helping to keep them in place. The mesentery also provides support and protection to the organs as the crayfish moves and carries out its activities.
What keeps all the organs in a crayfish attached?
glue
What are the two large lightweight organs of the respiratory system?
These two organs are the lungs.The lungs are these two organs.
What is the major function of the exoskeleton of a crayfish How is the exoskeleton an adaptive advantage to the crayfish?
The function of the exoskeleton is to protect the internal organs and support the crayfish because it is an invertebrate.
What is the common feature between gills and lungs?
Both of them belong to Respiratory System.Lungs are the respiratory organs of human beingsGills are respiratory organs of fishes
Organs in the respiratory and circulatory system?
The main organs of the respiratory system are the lungs. The main organs of the circulatory system are the heart, blood, and blood vessels.
What is attached to the organs of a crayfish that keeps them all together?
A thin membrane called the connective tissue holds together the organs of a crayfish. It helps keep the organs in place and protects them from damage while allowing for flexibility and movement.
What is the meaning of respiratory?
Of or pertaining to respiration; serving for respiration; as, the respiratory organs; respiratory nerves; the respiratory function; respiratory changes.
What are the common features of the respiratory organs in aquatic and terrestrial animals?
The common features of the respiratory organs in naquatic and terrestrial animals are:- (1) The respiratory surface is both are highly extensible. (2) The respiratory surface is fully permiable. (3) The respiratory organs are richly supplied with blood for complete diffusion. (4) Both the organs are highly protected #This is Bhargavi !!
How do the respiratory structures differ for crayfish and grasshoppers?
In crayfish, gills are required to perform respiration whereas grasshoppers get oxygen for respiration straight from the atmosphere.
What do the organs do in the respiratory system?
The organs in the respiratory system are responsible for oxygenating the blood and for expelling built up carbon dioxide.
What are the major organs in respiratory system?
The main organs of the respiratory system are the nose, pharynx, trachea, bronchi, and lungs.
