Large, slimy discoveries are not surprising finds in a cow field. Researchers found the largest known colony of clonal amoebas in a pasture near Houston, and the billions of single-celled organisms could help scientists better understand how these social amoebas cooperate over such a large spatial distance. (FYI, for other people with hopeful imaginations, the colony looks nothing like The Blob, or Slimer from Ghostbusters.)

Wow, that's a really huge amoeba! But does it really contain only one cell? Amoebas do.
If you notice the scaling tab in the upper left hand corner of the image, the entire amoeba is only about 200 micrometers wide (About 1/5 of a millimeter). That’s barely visible to the naked eye, and would be interpreted as a speck of dust without at least some magnification. Also note that the images is a generic amoeba image courtesy of Dr. Ralf Wagner, who is not mentioned in the New York Times article and therefore is not likely to be an image from the amoeba colony mentioned in the article.
