Testate Amoebae
Definition
Testate amoebae (Testacea, or Hyalosphenia) are amoeboid protists, differing from naked amoebae in that they inhabit a test, or shell.The test of the testate can be created entirely by the amoeba, in which it would create an organic, siliceous, or calcareous shell depending on the species of testate amoeba. These tests created entirely by the amoeba are known as autogenic tests Lousier and Parkinson, 1981
Habitat
This group of free-living microorganisms inhabit aquatic to moist habitats including: estuaries, lakes, rivers, wetlands, soils, litter, and moss habitats. They are able to live in both fresh and marine water, however, compared to naked amoeba, testate amoebae are less abundant in most soils. They thrive in soil environments that are moist and within forested systems.
