What marine animals depend on jellyfish for food?

Fish:

* Tuna: Some tuna species, like the bluefin tuna, feed on jellyfish when other food sources are scarce.

* Swordfish: Similarly, swordfish may consume jellyfish as part of their diet.

* Sunfish: These massive fish are known to eat jellyfish, especially the moon jelly.

* Sea turtles: Some sea turtle species, such as the loggerhead, are known to consume jellyfish.

* Sharks: While not all sharks eat jellyfish, some species, such as the thresher shark, have been observed consuming jellyfish.

* Seabirds: Certain seabirds, such as the northern gannet, will dive for jellyfish to eat.

* Other invertebrates: Many invertebrates, like crabs, lobsters, and sea anemones, also feed on jellyfish.

* Whales: Some whale species, like the humpback whale, have been observed eating jellyfish.

It's important to note that while many animals can consume jellyfish, they often aren't the primary food source. Many animals only rely on jellyfish during specific times of the year or when other food sources are scarce.

Additionally, there are some animals that specialize in eating jellyfish, such as the ocean sunfish and the leatherback sea turtle, which rely heavily on jellyfish for sustenance.
