What do Jelly Fish eat? And who eats them?

These Jelly Fish are the right way up!

Like boobies, Jellyfish come in all shapes and sizes and indeed, colours. But what do they eat? How to they catch their food and do they eat with ketchup? Or who eats them? What creatures find jelly fish  tasty?


First up, what are Jelly Fish? Are they actually fish? The internet reveals all: Jellyfish (also known as jellies or sea jellies or medusozoa) are free-swimming members of the phylum Cnidaria. Jellyfish have several different morphologies that represent several different cnidarian classes. Medusa is another word for jellyfish, and as such is used to refer specifically to the adult stage of the life cycle. 


Really? I thought Medusa was a lady with snakes in her head.... but I digress, what have we appeared to have learned here children? Jelly Fish are not actually fish. Fish are fish. Fish are also friends, not food. 

Okay, I told a lie, Jellyfish eat fish. Indeed, when ordering pizza, they order extra anchovies.
Jellyfish are actually carnivorous. They eat a healthy diet of  zooplankton, smaller fish and sometimes other jellyfish. Bigger jellies eat large crustaceans like shrimp.

This guy is simply here because he looks cool!

I may have written above that fish are friends and not food, we know that's not necessarily true - the same does not apply to Jelly Fish. Many sea creatures find jellies and the members of the Medusa family to be tasty treats. Like jelly is.


So fish like to eat Jelly Fish:

Starfish seem to like to eat them, but how the fuck to they catch them? Sneak up on them when they are dead? That's what sunstars do with octopus...



And there's always a hungry turtle around that's keen to try any fish once...

Hungry starfish eating an Octopus

When starfish go blue (on octopus)

I thought it would have been the other way around and this poor octopus would be eating the Starfish but the caption that comes the photo reads:

"her job of guarding her eggs is finished; her emaciated body is devoured by a swarm of sunstars".

So the circle of life in action on the sea floor as the octopus just apparently gives up,

Like Padme in the Revenge of the Sith,

Tastes like fish?

Sunstars, starfish, it makes for an unexpected picture.

Look at that eye staring at you.

Is it a look of 'laying back, thinking of England'? It actually looks like a dead eye, I suspect the octotpus died a natural death and then the Starfish have scavenged it for a meal.

What else do Starfish eat? Cockle anyone?

Here's a star fish in captivity that's been fed.

And just to cap off, this starfish caught himself a fish! His chips got soggy however...
