Caption:
Magnified 1000X, this 2002 scanning electron microscopic (SEM) image revealed some of the ultrastructure exhibited by a number of Hartmannella vermiformis amoebae trophozoites. The amoeba assumes this trophozoite stage, which is its vegetative phase, in which it spends time feeding, moving about, and reproducing. This free-living protozoan moves in response to chemical signals in its environment by extending pseudopodia, or false feet. See the link below for more on the study that inspired the creation of this image.
