I have a bucket in my garden, filled with very dirty water. In it, I discovered what looks like a bunch of 15 or 20 large maggoty things with long, thin protuberances, and tangled into a ball. They are floating just below the surface and each one also has a long tube coming from one end, some of which are breaking the surface and may be breathing tubes. They are continually writhing. Does anyone know what they are or what they will become?
I have tried to upload a short film which shows their movement, but the 'load images' facility doesn't seem to allow it.
