Some jellyfish even eat other jellyfish!

What is the food chain of a jellyfish?

Jellyfish play an important role in the oceanic food chain and the ecosystem. Jellyfish are carnivorous and feed mostly on zooplankton, comb jellies and other jellyfish. Large species of jellyfish feed on large crustaceans and other marine organisms. Sea turtles, sunfish and spadefish prey upon jellyfish.

Does anything feed on jellyfish?

Leatherback turtles and ocean sunfish have long been known to gorge on jellyfish, gobbling hundreds of them every day. But leatherback turtles and ocean sunfish are exceptionally big. Many scientists considered their size to be a special adaptation for living on jellyfish.

What are 3 predators of jellyfish?

What would happen if jellyfish went extinct?

Globally there are huge numbers of jellyfish in the oceans. In recent years, studies have suggested that when jellyfish blooms die-off, massive quantities of jellyfish sink out of surface waters and can deposit as “jelly-lakes” at the seafloor, choking seafloor habitats of oxygen and reducing biodiversity.

Do sea turtles eat comb jellyfish?

Predators and Prey While their nematocysts and colloblasts do help them defend themselves, plenty of animals manage to catch and eat jellies: more than 150 animal species are known to eat jellies, including fish, sea turtles, crustaceans, and even other jellyfish.

It uses it’s so-called “coelenteron”, which is doing the same thing as your stomach and intestines. Here we find a lot of enzymes that will help it digest the food. The food is digested through the cells inside the stomach and the rest is being spat out again. The jellies have not blood or vessels so there’s no real circulation system in place.

How do Jellyfish kill their prey?
