Detailed explanation-1: -Jellyfish are not really fish, of course, because a fish’s anatomy is centered around its backbone, whereas the jellyfish is a dome-shaped invertebrate.

Detailed explanation-2: -But despite their name, jellyfish aren’t actually fish-they’re invertebrates, or animals with no backbones. Jellyfish have tiny stinging cells in their tentacles to stun or paralyze their prey before they eat them.

Detailed explanation-4: -The simple digestive cavity of a jellyfish acts as both its stomach and intestine, with one opening for both the mouth and the anus. These simple invertebrates are members of the phylum Cnidaria, which includes creatures such as sea anemones, sea whips, and corals.

Detailed explanation-5: -Jellyfish are invertebrates meaning they do not have a backbone. In fact, jellyfish have no bones at all, instead they have layers of cells that make up the walls our their flexible outer shape. Inside jellyfish contain jelly, which is made up of salt protein and mostly water.
