Jellyfish are preyed upon by a variety of animals, including sea turtles, sunfish, and certain species of birds. Some other marine animals that eat jellyfish include:

• Ocean sunfish: These fish are predators that eat various foods, but their favorite delicacy is jellyfish. Since jellyfish are almost entirely water and low in calories and nutrients, fish as large as sunfish eat a significant amount of them to support their weight.

• Grey triggerfish: These fish are known to eat jellyfish naturally.

• Seabirds: Some species of seabirds, such as fulmars, have been observed consuming jellyfish. They peck the inner tissues of the jellyfish to avoid their tentacles. Since jellyfish are 95 percent water, predators have to consume them in large amounts to get higher dietary nourishment.

• Whale sharks: These sharks are known to eat jellyfish.

• Crabs: Some species of crabs, such as arrow and hermit crabs, eat jellyfish.

• Whales: Some species of whales, such as humpbacks, eat jellyfish.

• Other jellyfish: Some species of jellyfish are cannibalistic and eat other jellyfish.

Jellyfish are venomous, but they are 95 percent water and low in calories and nutrients. Despite this, they are still an important part of the marine food web and are preyed upon by a variety of animals.
