Jellyfish are carnivorous animals and their diet primarily consists of small sea creatures. Here is a list of some of the typical foods jellyfish consume:

1. Plankton: This is the most common food for many jellyfish species. Plankton is a collection of small or microscopic organisms that float or drift in fresh or salt water, including tiny animals (zooplankton), algae (phytoplankton), bacteria, and viruses.

2. Small Fish: Some larger species of jellyfish eat small fish. They catch them using their long, stinging tentacles.

3. Other Jellyfish: Certain species of jellyfish are known to consume other, smaller jellyfish.

4. Small Crustaceans: Some types of jellyfish eat small crustaceans like shrimp and copepods.

Jellyfish capture their prey using their tentacles, which contain special cells called cnidocytes. Each cnidocyte contains a stinging thread, or nematocyst, which is used to immobilize or kill their prey. Once captured, the prey is moved to the jellyfish’s mouth, which is located on the underside of its bell-shaped body. From there, the prey is transported to the gastrovascular cavity where it is digested.

It’s worth noting that jellyfish don’t actively hunt their food, but rather drift along ocean currents, capturing food as it comes into contact with their tentacles.
