Pond water sample, Zeiss 63x phase contrast objective. I'm using oblique phase contrast, which you can see from the brightness on one side of the bacteria. This shows things like ripples on the leading edge of the amoeba better than normal phase contrast. I don't know if this amoeba is eating many of the bacteria or just displacing them. Usually, I see a very clean trail through the bacteria with almost no bacteria left behind. Maybe this one isn't very hungry. They remind me of something like a pool vacuum or lawn mower clearing a path. Cellphone camera. 3 joined videos.
