What eats jellyfish

Many predators are out there

Jellies have been around for millions of years and over that time many predators have relied on them as a staple food source.  Most filter feeders will eat the early stages of a jellyfish, the egg and planula larva which are free floating. Depending on water conditions, the egg and larva swarms create large nutritional seasonal abundance.


A variety of lifeforms in the wild eat jellyfishes. Fishes like sunfish, whale shark, chum salmon and tuna fish eat jellyfishes.

Reptiles like the leatherback, loggerhead, Green and hawkbill turtles eat jellyfishes.

Mammals like red tailed foxes and penguins consume jellyfishes that become washed up ashore and even members of the jellyfish group such as other jellyfishes, anemones and small molluscs eat jellyfishes. 

Did You Know?

Scientists have discovered a jellyfish which can live forever. The Immortal Jellyfish known scientifically as Turritopsis dohrnii is now officially known as the only immortal creature. The secret to eternal life, as it turns out, is not just living a really, really long time. It’s all about maturity, or rather, the lack of it.

The Food Chain for Jellies (Predators)

Turtles eat Jellies

Three species have been affected greatly by plastic pollution as they often mistake plastic bags for jellyfish. On attempting to ingest the bag they can suffocate on it, and this often happens with the greens and the loggerheads whilst they are sub-adults, taking them out of the food web early. Consequently, the predation pressures commonly exerted on jellyfish are removed allowing the plague populations to grow.

Loggerhead (Caretta caretta)

  1. Mainly carnivores.
  2.  World’s largest hard-shelled turtle. up to 440 lbs, average at 289 lbs. 
  3. Loggerheads are the second-largest turtles in the world and the largest hard-shelled turtles on earth, the leatherback turtle is larger, but with a softer shell.
  4. Broadest range of any sea turtle. Atlantic, Indian, and Pacific Oceans, Mediterranean Sea.

The Green Turtles (Chelonia mydas)

  1.  The Green and leatherback nesting sites in the eastern basin around Greece and Cypress
  2. Juveniles eat invertebrates like crabs, jellyfish, and sponges.
  3. The green sea turtle is the only species of sea turtle that is predominantly omnivorous as an adult.
  4. These turtles can grow up to 5 feet and weigh in at 700lbs

Leatherback (Dermochelys coriacea)

  1. The leatherback has no known nesting sites within the Med and the closest breeding spots are along the coast of the Northwest Atlantic. 
  2. Largest of the sea Turtles and weigh as much as 2000lbs and 6ft long
  3. Throats and mouths are lined with papillae (spine like) to protect against stinging cells of the jellyfish



Other fish that eat Jellies

Countless fish rely on immature and mature medusa jellyfish for a source of nutrition.

Sunfish (Mola mola)

  1. Mainly feed on jellyfish.
  2. The largest and heaviest bony fish in the world and can reach an extraordinary 5,000lbs weight
  3. These fish traverses all the major oceans on Earth except the Arctic and Antarctic oceans. Sunfish are pretty commonly found all across the Indian Ocean, as well as the Atlantic and Pacific Oceans, and across both coasts of the United States. 

Grey Trigger fish (Balistes capriscus)

  1. Grey Trigger fish (Balistes capriscus) and the Sunfish (Mola mola) whose populations are similarly affected by plastic ingestion. 
  2.  Found in the western Atlantic Ocean from Nova Scotia south to Argentina, including Bermuda and the Gulf of Mexico.
  3. Triggerfish can grow to be up to 13 pounds, 28 inches fork length.

Birds

  1. Albatrosses
  2. Fulmars
  3. Birds

Fishes

  1.  Tunas
  2. Whale shark
  3. Ocean sunfish
  4. Grey triggerfish
  5. Sword fish

  8. Butter fish
  9. Bearded goby
  10. Herring
  11. Whiting
