Hitchhikers wanted - Acoels (ghost flatworm) and Trichoplax adherens

[Blarbus]

One man's trash is another man's treasure. I really like strange invertebrates, and I was wondering if folks had hitchhikers that they wouldn't mind scooping out and sending my way.

In particular, I'm interested in acoel flatworms that lay eggs for reproduction: for example:

Or a strange hitchhiker called Trichoplax adherens, normally seen as strange amorphous blobs stuck on glass eating algae.

Any help finding these critters would be greatly appreciated.

Thanks!
