Update: thank you so much :) apparently, they are dead and so harmless that the local kids pick them up and throw them at each other. PSA: don’t throw local wildlife at each other.

I like that you referenced the ctenophore in the picture as "they", because ctenophores are hermaphroditic, they can carry both male and female reproductive organs.

Ctenophore - comb jelly. Not a true jellyfish and completely harmless

Yes, ctenophores are a completely different phylum and may be the sister to all other animals.

It's a bit difficult to tell from these pictures but I think this one might be a species of Beroe.

Beroe is a genus of ctenophores without tentacles that are specialized to predate on other ctenophore species.

Mnemiopsis leidyi. Sea walnut, non native species of ctenophore in the Med. harmless
