Why jellyfish is not an animal?

While they might not look like the typical furry or feathered creatures we think of, they are classified as animals because they meet the criteria:

* Multicellular: Jellyfish are made up of many cells that work together.

* Heterotrophic: They can't make their own food and must eat other organisms.

* Eukaryotic: Their cells have a nucleus and other membrane-bound organelles.

* Reproduce sexually: They create offspring through the combination of sperm and egg.

* Move: Even though they drift with currents, they can move independently using their muscles.

So, while they may lack bones, a brain, and a traditional body plan, jellyfish are indeed animals!
