Frontonia sp., Phase contrast (compare to dic)

Post by Charles Krebs »

When I was doing the Campanella yesterday, this Frontonia (I think!) was cruising around the slide. I took a few shots. While it was a different time and a different specimen, I think it is worthwhile to compare it with the DIC image of one I made a while back. ... highlight=

It can also be compared with an oblique brightfield Frontonia posted on the old forum: ... ht=stomach

Again, this is far from a direct comparison (so don't read too much into it), but I think it does illustrate some of the differences in the way certain features are seen with different lighting techniques.

Hi Charles,

this is sheer beauty!!! But Frontonia? One should see the mouth slit, shouldn't one? I would rather vote for Tetrahymena.

Ditto, mainly because of the rather pointed anterior, I am assuming. Though both the Frontonia and Tetrahymena exhibit an oral cavity, the presence of one is not seen in the photograph as I can see. The Frontonia seems to have a more rounded anterior too.

Regardless of the species of critter, a quite colorful and excellent photograph as usual. :D
