My son wants to know if jellyfish are immune to the sting of another jellyfish. Why?

Answer 1

There may be some species of jellyfish that are immune to the stings of a few specific other species of jellyfish (including their own), but in general, jellyfish are not immune to the stings of other jellyfish.

There are quite a few jellyfish that actually prey on other jellyfish, stinging and capturing them with their tentacles.

For example, an invasive species known as the pink meanie (Drymonema dalmatina) has moved into the Gulf of Mexico, and may have a significant impact as it preys on native species such as the moon jellyfish (Aurelia aurita).

Here is an account from the BBC Science & Nature site about observing a lion's mane jellyfish (Cyanea) devouring other jellyfish: http://www.bbc.co.uk/nature/animals/features/142index.shtml

Answer 2

Maybe because your son is interested in jellyfish.

You asked me why your son wants to know something about jellyfish and I am the only one who answered your question and you give me a thumbs down?

Answer 3

I depends on the species I assume. However, I would expect most would have resistance to the stings. Many fish that live in coral reefs with stinging sea anemones are able to live within the anemone because it acquired resistance over time.

Answer 4

They are . . . otherwise a jellyfish would kill itself whenever its tentacles touched its own body.

Answer 5

I would assume they can create antibodies for their own poison...
