* They move: While some jellyfish drift with currents, they can also propel themselves through the water using contractions of their bell-shaped body.
* They eat: Jellyfish are carnivores and feed on small organisms like plankton and fish.
* They have a nervous system: They are able to sense their surroundings and respond to stimuli, unlike plants.
* They reproduce: Jellyfish reproduce sexually, unlike plants which primarily reproduce asexually.
Why the confusion?
* Lack of movement: Some jellyfish species are very passive and can appear to be swaying gently like seaweed in the water.
* Translucent body: Their bodies are mostly water and can appear clear or semi-transparent, which might resemble the appearance of some aquatic plants.
Ultimately, jellyfish possess all the characteristics of an animal and are distinct from plants in their anatomy, physiology, and behavior.
