The video was taken on the 17th June 2021 - it shows Daphnia in my wildlife pond massing together to form spirals at the surface.
The rippling effect was caused by the Daphnia.
They were still at it today ...
Sorry it's not the best shot video
 
Interesting. Maybe give them a slight stir the other way and see if they then go with that, or if they restablish the original direction.

I like the idea they are "dancing widdershins" mind you :)

I almost used the term widdershins, but thought it too quirky!

Wonder if, in the southern hemisphere Daphnia do their thing clockwise?
 
Amazing!
A friend of mine had daphnia in their birdbath. How did they get there? Attached to bird's feet, supposedly.
