Please could you tell me what kind of worm this is? It came out of our small plastic swimming pool. There were several worms and I put one on a leaf to make a picture..

thank you in advance!

Answer
Hi Priscilla,

Unfortunately I do not see any picture.
red small worms are often "muggenlarven".
However is swimming pools you need to make sure they are not of an other type as some worms can be harmful http://nl.wikipedia.org/wiki/Schistosomiasis.
Did you disinfect the pool with chlorine?

If possible, please sent the image.

Thank you in advance.
Kind regards,

Raf
