Salpingoeca fusiformis – Cell Reproduction
This tiny protozoan, a member of the Order Protomonadina, family Bicosoecidae is one of the genus Salpingoeca. This collar flagellate and others like it have always interested me because of the vase-shaped lorica that they construct. At only 5 micrometers in diameter, their features are not well def...

Amoeba - Volume 7 – Mayorella
Here we have a common genus of amoeba, Mayorella. There are many species in various forms and sizes. Three specimens are shown here. The first three images are the same size of field (130 by 130 micrometers) so the size difference is quite apparent. The last image is field size is 210 x210 micromete...

Amoeba - Volume 6 – Amphitrema with beaded filipodia
After obtaining these images the work to determine what I had found began. It was obviously a testate amoeba with a test transparent enough to see through. The extremely long fine filopodia with a series of beads were like nothing I have seen before. Were these beads of axopodial cytoplasm like thos...

Amoeba - Volume 5 – Gromia fluvialis.
Finally, a testate amoeba that I can put a name to. This amoeba has a test around 20 micrometers diameter and long pseudopodia in the form of filopodia, up to 90 - 100 micrometers. While stationary, the filopodia extend out in all directions. They are in a state of constant change, extending and ret...

Amoeba - Volume 4 - Two tiny testate amoeba.
We get two for one here in a small field of detritus. Both show well in the same plane of focus in the top image. The lower gray amoeba is projecting a pseudopodium larger than its entire body which is roughly 8 by 12 micrometers. The amoeboid is very similar to the subject in my Volume 1 post. Howe...

Amoeba - Volume 3 - A tiny amoeba with flagella.
This tiny amoeba, only 8 by 12 micrometers in size has a pseudopodal projection that started out an oval and expanded to a circle. It was the way that I recognized this little smudge as a living amoeboid. My eye had initially been drawn to this area of my slide by the presence of the Peritrich to it...

Amoeba - Volume 2 -Testate amoeba.
This amoeba is a very slow mover. It projects a wide pseudopodium in the direction it wants to move. In these images, the movement was to the upper right-hand corner. Its size is roughly 45 -50 micrometers in diameter. I believe that it is a testate amoeba due to the pile of material moving along wi...

Amoeba -Volume 1 – A strange testate amoeba.
I begin this series with the most unusual ameboid subject that I have seen to date. It is circular, stationary, colorless, very flat and it has short filose pseudopodia. It also seems to have projected a large circular pseudopodia, if that is what it can be called. Dozens of live bacteria inhabited ...

Cyclidium glaucoma feeding.
Cyclidium glaucoma feeding. It is good to be back after a very long absence. I see that submissions have undergone some changes. Hope I did it correctly. I have for your review some images of the protozoan Cyclidium glaucoma (Kahl). These are the first protozoan darkfield images with a, new for me, ...

A Vanadinite crystal in R-DIC
Back in February of this year I posted two images of vanadinite crystals. The subject of this post is in the top image of that post. The image showed small crystals that had grown on it’s face surface. I thought this was odd along with the lack of smoothness on the crystal surfaces. I have revisited...
