Planaria are just the most commonly recognized member of the phylum Platyhelmenthes (flatworms). There are countless forms that do not have the exaggerated triangular head we associate with planaria.
This is definitely a mass of flatworms feasting on the dead body.
When I taught a biology course, I collected flatworms for the class by placing a piece of raw meat in a stream for a day. When I came back to collect them, the piece of meat was covered with them very similar to what you see here with that dead shrimp.

Not to healthy ones, but sick ones they well overwhelm and kill. I've seen them kill apple snails too. If you get a huge number they can get in the shell with them and weaken them.
I'm testing a product called PraziPro that is supposed to be invert safe, but kill planaria and hydra. I'll post back in a few weeks with the results.
I've never seen planaria like that before....the planaria outbreak I had several years ago were just tiny little thread like worms which weren't tough to get rid of.
Yes it's a cherry shrimp and not the only one to die according to the post about it on another forum. The person who owns the tank keeps a puffer in with them and I thought the shrimp looked almost chewed.....perhaps the puffer is a brackish puffer and he's keeping freshwater shrimp in there too. Puffers are such messy eaters it doesn't surprise me the tank would be full of worms.
It's a forum I don't frequent often because their idea of shrimp keeping differs greatly from mine and most of us here.
Freshwater planaria can look like the ones in that picture. You can even get them mail order from biological supply houses, which supply them to high schools and colleges.

Keeping any kind of shrimp with a puffer is a guaranteed death that is such a shame.
