new rotifer (for me). ID suggestions?

Post by Charles Krebs »

Large, but almost like a balloon... very little inside. Don't recall seeing one of these before. It appeared to anchor itself by a very thin strand at the tip of the foot and swung back and forth as it fed.

Very nice Carlos; but I am so ignorant as you respect this rotifer.

Jan,

Thanks! Not only did you put me on track as far as an identification, but in searching for a reference I came across a very nice site that I think will be very helpful for identification purposes in the future.

Charles, thanks for the links.

There appeared to be a typo in your posting -- both links went to the same place, the one for the specific critter.

I edited the second link to point to what I think you intended. Please let me know if not correct. Thanks!

Very nice images Charles. The more I see, the more I question what life is.

And a great link you found too. :)

Rik,
Good... thanks!. Need to remember the "copy" part before doing the "paste" part.:wink:

Mitch,

Well, now that you are peering through a microscope at least be prepared for the lines between animal/vegetable/mineral to get a little fuzzy. :shock: :wink:

After over 4 years of intense interaction with birds, I was already questioning everything I ever heard about animal intelligence. Now, in just one week, I am questioning what is a plant and what is an animal, and I am seriously beginning to question who is looking at whom...

Michel,

Yes, that appears to be a good possibility (or perhaps Asplanchnopus dahlgreni). I should have measured it before posting. The body measures just over 650 micron, so much too big for Gastropus hyptopus.
