Mucocysts have a herringbone pattern of subunits and are surrounded by a membrane that fuses with the plasma membrane. When the mucocyst content is extruded the content expands (see Hausmann, Protistologica 8:401-412, 1972 for details. TEM taken on 8/12/67 by R. Allen with Philips 200 operating at 60kV. Neg. 19,200X. Bar = 0.2µm. The negative was printed to paper and the image was scanned to Photoshop. This digitized image is available for qualitative analysis. An unprocessed, high resolution version of this image (CIL:34731) is in the library and available for quantitative analysis. Additional information available at (http://www5.pbrc.hawaii.edu/allen/).
