again a tintinnid ciliate

[Franz Neidl]

Currently I have many tintinnids in my samples. This is a ciliate with a lorica which is 100 µm high. Somebody knows the name of the species?

Hello Franz,

Can't help you with ID..what magnification and what type of lens pleaes...a lovely picture

Thank you John! I used a 40x PlanApo Objectiv in DIC, the PLI 2x projection eyepiece from Nikon and an electronic flash.

Wow Franz, a beautiful image. Was he free swimming, lorica and all?

Franz,

another fantastic shot. I have no idea of the species. I love to see live tintinnids, but without a flash it is frustrating trying to get good photos!

thank you!

Franz,

Another fascinating specimen, nicely photographed.
You certainly have an ability to get interesting subjects on your microscope. Could you give a brief summary about how you work once you have collected with the plankton net? How do you isolate and separate these subjects and get them on a slide? Is it simply done with a stereo microscope and pipettes?

Hello Charles,

thank you very much for your kind words. I dont use the classical method with the stereo microscope, but I make at home a concentration from each sample with a cup-shaped planktonnet (meshsize 33 µm). Afterwards I give with a pipette two big drops on a slide and observe it on my microscope with the 4xObjective (this objective is essential for my work). If I find something interesting I cover the 2 drops with one coverglass (24x60 mm).
If I dont find something I clean the the slide and give two new drops on the slide...and so one.
If somebody wants I can describe better some of the details of this workflow.
