I dont know what this specimen is.

I collected a sample from a fresh water stream with bits of water plants in it, i notaced there where very faint up to 1cm long worms in it - as i held the jar up to the light

I decided to prepare a slide with one of these worms.

It seems to move around a fair bit, it dosent seem to like the light very much, which makes it harder to photograph.

This is a photo of what seems to be its head, or front side.

4x objective

Anyone have any idea on this one?

Hi Adrian

that's an oligochaete of some sort. May be a Chaetogaster.

Thanks for your reply Bernhard.

I just recently notaced it has seemed to have split into two by itself, and they are both acting as individual organism's with head and eyes.

they are eating like crazy!, and they allso seem to be interacting with eachother, something is bound to happen.

This is really interesting.

Adrian,
I'm not a big worm fan... but these guys can be fun to watch. They have a voracious appetite, and are always on the search for food. I always take a look at their insides to see what has been on the menu recently.
