More random vermes

[ptychoptera]

I'm assuming this is just another hopelessly unidentifiable flatworm. Just curious if perhaps our resident worm expert might be able to narrow it down any. For instance: is it acoelomorph or 'turbellarian'?

Size: 3mm

Polychaetes are my babies; I know just enough about flatworms to get into trouble with the real experts.

Acoels & polyclads are both included in the Turbellaria. There are also tiny nemerteans that look like this so I'm really not sure. I'll forward the pic to a colleague for his opinion.

Here's a couple of aquarium articles on flatworms -
