Abstract
We analyzed symbiotic protistan engulfment systems using the method of fluorescent imaging. Symbiotic protists can be divided into two protistan groups, Type S (protists that contain uniformly small and spherical vesicles) and Type L (protists that contain vesicles that vary in both size and form). This classification corresponds not to the taxonomic classification, but to the micro-habitats of the protists. Our results suggested that these protists might have adapted to different resources in the hindgut environment of lower termites.
