Frontonia dividing. Collotheca rotifer. Salpingoeca.

All taken with: Olympus BHS. Olympus 60/1.40 S Plan Apo. Olympus NFK 1.67x photoeyepiece. DIC illumination with electronic flash. All considerable crops from full frame (especially the top three).

This Collotheca rotifer was pretty "nervous". At a slight change in focus (because of the slight "pressure" change sensed through the immersion oil) it would withdraw and pull back. But I liked the overall "setting" and found it interesting when it gradually extended again and began to unfold the fine long "cilia".

Your technique for using the a superb, but inherently tricky, oil immersion lens on living subjects is peerless. Wonderful pictures, that Collotheca made my eyes pop!

Hi Charles,

Great pictures, your DIC is very good even with a 60/1,40. Ciliates are beautiful and it is the best Collotheca pic I see !

A+
