 This is a magnification of a drop of turtle pond water from Caltech. It was obtained in recitation on 4/9/19. The TA collected the sample. Given the relative size of the detritus(the elongated white thing) I think that the black dot is a protozoan belonging to the eukarya domain. Bacteria or archea would be much smaller. #caltechbi1
