Hyalotheca dissiliens, spirogyra and rotifers

Post by Charles Krebs »

My most commonly used current collection location (as was the case last year about this time) is full of Hyalotheca dissiliens (a colonial filamentous desmid), mixed in with spirogyra.

Here are a few new shots, plus some shots of rotifers that fed on the spirogyra.

I watched the rotifers in these last two pictures methodically move along strands of algae. They would stop at each cell, pierce the cell wall and suck out the contents. In this last shot you can see the empty lower cells and the indentations where the rotifer cut into the cell.

A remarkable observation of those rotifers taking their chlorophyll neat, beautifully presented and with helpful comments too. Thank you Charles.

Charles, thanks for teaching me something about Rotifers and doing so with beautiful images. Now I have something else to look for when observing Rotifers! :D

Thanks for the comments!

I was a pleased to observe the rotifers dining on the spirogyra, and a little surprised I had not seen it before. It was also interesting in that the first slide that was observed (and where I took these last two rotifer images) was a very "deep" slide, that really had too much water in it for some magnifications. A second slide was made with less water, but the rotifers (even though they still had plenty of room to maneuver about) did not seem "comfortable" enough to resume their feeding.

Hi Charles, did you use immersion objective/condenser for those pictures?

Hi Charles, can you please help me? What is the name of this beautiful rotifer, I have also discovered a way, but it can lead to classification in any book found.
