Little Venice is drying out and the other day I managed to get a bit closer to see what was going on. I was surprised to see little plants sprouting out of the mud and rugs of green slime draped over the path.
I looked up green algae, as that’s what it looked like, and found out that filamentous algae, or pond slime, is algae that looks like thin green threads. It supports many microscopic animals and provides food for other small animals. The slime floats on the surface of the water and then when the water is dried out, it dies and forms a white crust. I have seen this happening as puddles dry out.
