What the....?

During a recent visit to Woolsington Ponds watching Damselfly I saw a couple of these creatures swimming eel-like just below the surface. They were 4"-5" long which they could vary by making themselves thinner and longer. They also looked to be flat across the back rather than rounded. Like nothing I have seen before


Any ideas?

Well developed Newt tadpoles?

I think they may be horse leeches - they can swim, and well as the more typical looping movement (and they can leave ponds and move overland)

Phil, was beginning to wonder after your recent post re foreign worms. Was a bit disturbed because kids were in the pond with them.

I think they could be flat worms, I had one on my blog it was out the water,

I think these are leeches too - especially from your description of being able to vary length: http://www.youtube.com/watch?v=V6N7wDKEV3w
I shouldn't worry too much about the danger they represent - if anything leeches can be good for the circulation!!!

People - quite naturally I guess - find the idea of these blood sucking creatures a bit disgusting but actually they won't do any real harm & will fall off once they've had enough.

Brian, I must admit that was my first guess.
Paul, thanks for the info I'll reassure the bathers the next time I see them.

I'd guess at leeches Definately look and sound like that's what they are
