Micromollusk - Snail

I am tired of waiting for the ice to melt on the ponds and lakes where I live so I decided to ask the local aquarium store for a water sample. Found a lot of stuff in there and here is the first find, a micromollusk. Around 2.5 mm in diameter.

Decided to try the difference between the UplanFl4X and the Mplan5X. The first being of biological type and the other being a metallurgical objective. The 4X does not require a cover glass either, so in theory they should similar expect for the slightly higher magnification of the Mplan.

Here is the Uplanfl4x. Zeiss and Ikea illumination. Stack size is 66.

MPlanFl5X. Stack of 51.

I decided to zoom in with the MplanFL10x to get a better look. Stack of 47.

Once zoomed in I noticed a lot of green algae growing inside. Very difficult to see with plain light and external illumination so I decided to try ultra violet (UW) illumination.

Objective UplanFL4X. Stack of 33.

UplanFL10X.

UplanFL20X

In black and white for a more galactic look....

Wonderful images. Really like the first two fluorescence.

Thank you Charles and Smokedaddy. It is interesting that some of the objects looking like glass or crystals in the VIS image still fluorescence in bright red under UW. They must contain chlorophyll despite looking like glass. I suspect these are diatoms.
