Leech or worm in my pond?

[Trehunsey]

I have trawled the net and am still baffled.... I know some of you lovely helpful folks on here will help!

The wind today had blown some of our lillypads over so my hubby flipped them back - only to find 3 or 4 brown critters that looked suspisciously and frighteningly (for me) like leeches! If they are, they are - it's nature and I will leave them be anyway but I am (to be honest) a little worried for my frogs and newts.

No pictures (sorry) but they are 1" or so long and then, as they move (much like earthworms do - stretching out) they are maybe 2" long. Flattish at one end and pointed at the "head" end - at least the end that seemed to be going first! Pretty thin.... Any ideas from this totally rubbish description?!?

I'm sorry, but wriggly things aren't really a love of mine - I love every creature but I much prefer those with legs! - so I didnt really "study" these beasties very well. Whatever they are, how did they get to my very small, man-made pond?!? No fish - just nature and a very large number of frogs and newts.

I asked about these critters a while back and if they are little tiny things they are not leeches they are something harmless, I'm racking my brains but at the moment can't remember what they are called.Just looked at the size of yours and that does sound big enough for a leech in which case I don't know if its a problem or just part of pond life.

Sound like a flatworm harmless and natural pond life.

From your description these are leeches. Flatworms (Planaria) are smaller and do not extend. The small aquatic leeches are harmless, feeding on small invertebrates, and are part of the natural pond fauna.
