Charlie g, have missed your posts. Welcome back and good observation about surface coatings of attached protists. I have observed similar.

Are you still collecting samples with your four legged companions?

Pat, super video. I often see several rotifers in a specific sample but never a "Herd" like this.
McConkey, these are all female, and you can often see the paired ovaries on either side of the gut.
Actinophrys, you certainly know what to look for.

Re: A herd of rotifers!

I wonder what their metabolism is like and why these small creatures have to eat so much.
Probably because what they eat is so small :)

Nice images.I think that might be the intestine.

All of the above. The first Ceratium is really great. That 60X WI is a treasure.
The camera I have now is quite good at freezing motion due to its high shutter speed and firing rate.
What camera and your technique please.
