What eats jellyfish?

What do jellyfish eat?

There are many kinds, or species, of jellyfish in all the oceans of the earth. The main predator of jellyfish is other jellyfish, usually of a different species.

But jellyfish also have a number of other natural enemies that like to eat them. These predators include tunas, sharks, swordfish and some species of salmon.

Sea turtles also like to eat jellyfish. In fact, each year many sea turtles become ill and even die from eating floating plastic bags and other plastic trash that they mistake for jellies. That is one of the reasons why it is important to keep trash out of the world’s oceans.

So, what do jellyfish eat? Most jellyfish prey on tiny sea creatures called plankton—but some types attack and ingest smaller jellyfish!
