Help me to identify it.

Hi,

This is a specimen that I found in a sample water from a lake, I do not know the name. I think it is 0.3-0.7mm long.

Nikon CF 10x 0.3 NA, dark field, all images staked with ZS.

When it was alive:




When the drop of water evaporated, then I added more water:




When all water evaporated, this looks bigger because it is a crop to remove some artifacts at the edges (from the stacked), after the crop the resize:




Comments please.

Hello Rogelio,

It's an ostracod perhaps a Cypris but the precise identification is difficult
