Jellyfish do not have collar cells. Sponges have collar cells, and yes, they are used for filter feeding.
The moon jellyfish has a feeding tentacle that hangs at each corner of its mouth. The tentacle has stinging cells that are used to capture small prey and drag it to its mouth.
An animal with collar cells, an osculum, and spicules is likely a sponge. Sponges are simple aquatic animals that filter feed using collar cells and have a central opening called an osculum through which water exits their bodies. Spicules are tiny, hard structures that provide support and structure to the sponge's body.
Jellyfish typically have 36 chromosomes in their cells.
water cells
Epithelial-like cells in sponges help control filter feeding by lining the channels and chambers where water is drawn in and filtered. These cells have specialized structures like microvilli and cilia that aid in capturing food particles as water flows through. By regulating the flow of water through these channels, the epithelial-like cells play a crucial role in efficient filter feeding in sponges.

collar cell- choancyte that is most likely in sponges
Jellyfish are composed of cells just like any other organism is.
The stinging cells in a jellyfish are located in it's tentacles.
Choanocytes (also known as "collar cells"). Choanocytes are found dotting the surface of the spongocoel in asconoid sponges and the radial canals in syconoid sponges, but they comprise entirely the chambers in leuconoid sponges.
