scums
Pond's filmy layers
Scums is the plural of scum—the frothy or filmy layer that forms on the surface of liquids, as when boiling or fermenting.
More commonly, scum refers disparagingly to despicable people: Those scums cheated us out of everything.
The plural scums is less frequent than the collective singular: pond scum, the scum of the earth.
