These were from a slide that sat on the pond floor for about a week and a half to 2 weeks. I'll post the stills first, then work on getting the videos up as well.

WOW! That is exactly what it was! I would never have found it on my own! So, it really does have "hairs," and why is it polka dotted? Don't reply just yet, though, 'cause now I want to look it up.
Just pointing you in the right direction. The thrill is in the discovery and learning.

Cool! Well, not a lot of information to be found, but found what I wanted to know! So this little critter is a beneficial pond organism -- a sludge-eater! The "dots" are oil deposits from things it's ingested. Is that just how they [the dots] manifest as they are ingested, and are they dependent on the environment it came from? And the "hairs" are for locmotion.

@Meyer Jordan And when you consider that it (there were actually 2 of them -- one was HUGE and hard to get to stay in one place to photograph it) was on a slide, sitting on the pond bottom -- what does that tell you about its function in the pond? Rhetorical question.

Shows that for all of the advances in science that there is still so much that is unknown and to be discovered and learned. I have seen sources that state that the colored dots are glands and whose function, as yet, was still unknown. All of the creatures in the Annelid (worm) family are detritus consumers. They are a very important part of a pond's eco-system.

@Meyer Jordan Thanks for the link. I couldn't view the videos though, because they require FLASH, which isn't available for iPad.....

I have total respect for worms (the annelid kind, that is) and when I dig, I use a fork instead of a shovel! In fact, was just digging in the turtles' "worm pit," but not all of the wigglers I found today will live to see another day -- turtle food -- circle of life!

Not a nematode, though it is a sludge-eater. It's actually an Annelid, which is what earth worms are, and it is beneficial.

Thank you Meyer . I only got to see one video sent to fb at least I was almost on the nail it being a subs pecies , I always appreciate the lessons my friend .
I did say that it was a sludge eater and thus beificial Maggie but not a sub species as Meyer correctly pointed out , did you learn anything from the Nematode website I sent you via PM its all very good information for you to take in .
As a matter great interest to me I'd like to know what the exact magnification you took the up close photos from ? (y)

@Dave 54 I'm pretty sure those pics were taken with the middle objective -- I can never remember the #'s, but think that is 100x (but it could have been 400x). I just recall that it was moving around so much that at 400x, I couldn't keep it in view long enough to be able to get pictures. Remember that I've been using my little Nikon CoolPix camera to take the pictures, so it's difficult to chase anything around for very long. It's set on "macro," and then I use the zoom to get the close-up shots. In the views where the pointer is visible, at least you have that to use as a size comparison.
