These Ostracoda, more commonly referred to as seed shrimp because of their appearance, are crustacea that were sent to us in a wastewater sample.
Ecologically, many ostracods are found in fresh water. As filter feeders, they feed primarily on plankton, alga, yeasts, fungi, bacteria, and detritus that can be swept by their hairy appendages. Seed shrimp are often found in in secondary clarifiers, after having been washed in by the rain.
What you see here is a close up of them in their shells. They seem to be able to wait out a chemical dump and other types of toxicities. So far, cupric sulfate and emulsified d-limonene seem to kill them, and we are determining the dose.

Light bulb filaments in Repetto window

Been wanting to take a photo like this for ages now but was struggling to find a clear filament bulb.
The dots around the filament are scratches on the outer glass of the bulb.
I used an ND2 + ND4 filter together to bring the shutter speed down to about 1/2000.
This shot was taken by breaking a light bulb and photographing the filament as it burns in the air. Normally bulbs are in a to vacuum prevent the filament from burning. By removing the glass and shooting several shots in quick succession I am able to capture this image.
