In this composite image, you can clearly see the differences in the shells of these two Amoebas. Both are constructed of dirt and sand from the pond bottom, but one is gritty while the other is smooth and almost transparent. The one with the gritty shell is obviously alive and alert - you can see the psuedopods (feet) protruding from the left side. The other shell is cracked. I suspect I caused the crack when I placed the cover slip over the water drop and crushed it. The Amoeba is still inside - perhaps pondering why the structural mishap? Back To Image Index Page
