  12. MorphologicalDiversityof TestateAmoebae Netzelia species secrete their own building material, called idiosomes, but they also use xenosomes which they modify and smooth.

  15. Testate amoebae are with a wide geographical distribution and a significant range of habitats. They are an abundant and diverse in various natural lakes, marshes, rivers, artificial water basins, in peatlands and terrestrial bryophytes, different types of soil and marine littoral. Thecamoebians occupy every sufficiently moist niche such as tree bark, caves, mines, and so forth. Testate amoebae can be divided into four ecological categories: freshwater-, moss-, soil- and marine-dwelling and have different morphological, biological, and ecological adaptations to their specific habitats.
