I like simple things. So to find this simple animal under my Foldscope was quiet a delight. I collected it in brackish waters in San Francisco.

At first site; it almost looks like a flatworm; say a planaria. But lookig closely – I think it might be Acoel. Watch for yourself:

Another view of the same animal; images with a foldscope.

I have some hints to believe this is an Acoel. I see the mouth structure but no real gut. With the special place Acoel hold in the phylogenetic tree; it would be find more species that we could grow and study. I will keep trying to ID this little one; if any of you have suggestions for identifications – please list comments below.

Cheers
