Some results from this weekend's project. To finally, after many years, to get a good image of this rotifer I first modified one of my Vivitar 283 strobes per Mr. Krebs's instructions. Then I had to extract a willing subject from my summers collection jars. All went well in the end. After many, many exposures I have finally a few portaits of this amazingly complex critter. Notice the differance in the beating heart. Thank you Charles and all you great folks that run this web site

Walter... pretty neat to see those cilia "frozen" while in motion, isn't it!

Are you sure you are not referiing to the mastax (the part that "crushes" the food) when you refer to the "beating heart"?

Glad you have the flash up and working. Look forward to see more live active critters. Happy to be of any help I can.

Hi Walter,

nice images! Just out of interest: what makes you so sure about it being a Habrotrocha and not a Rotaria?

Well, I am certainly no expert on these these rotifers and am most likely wrong about the heart. Regarding whether it is Rotaria or Habrotrocha is based on a low magnification image I saw on a website. It looked similar to me but I could be wrong, hence the ? mark in the subject box.

Walter,

Congratulations. Capturing individual cilia at the corona is a great accomplishment. - Tom

I think it is more likely to be Rotaria - Habrotrocha usually have pellet-like material plainly visible within their body. See my image at http://www.gpmatthews.nildram.co.uk/mic ... ifers.html for an example. You have indeed captured the cilia well.
