Most jellyfish are carnivores. Their main food sources are small animals such as:
- zooplankton (copepods, shrimp larvae, krill)
- small fish, fish eggs and fish larvae
- other small crustaceans
- sometimes other jellyfish
How they eat:
- Jellyfish use tentacles lined with nematocysts (stinging cells) to paralyze or kill prey, then move it to the mouth and digest it in the gastrovascular cavity.
Variations:
- Some species filter tiny plankton from the water rather than actively hunting.
- A few (for example the upside-down jelly Cassiopea) host symbiotic algae (zooxanthellae) that produce sugars by photosynthesis and provide part of the jelly’s energy.
- Deep-sea species may also consume marine snow or detritus.
If you want, I can give examples of what a specific jellyfish species eats.
