Limnofila is a genus of heterotrophic amoeba that belongs to the Cercozoa and forms its own order Limnofilida . They live in fresh water and feed on bacteria.
features
They are small, heterotrophic amoebas with very narrow, branched, granular filopodia . When eating, they are pressed against the substrate and are often spherical. Flagella , if present, are not visible under the light microscope.
The cristae of the mitochondria are flat. Bundles of 2 to 6 microtubules are located in the filopodia . The extrusomes are complex and structured concentrically. The two ultrastructural investigated species have two flagella stumps with a transverse plate at the base of the transition region, but no 9 + 2 axoneme. Microbodys , a centrosome and large grains are absent from the cells. The mitosis is a closed Pleuromitose, wherein the spindle apparatus outside the nucleus is located.
Systematics
Limnofila forms the order Limnofilida together with several unspecified DNA environmental samples, which together with a clade to which Massisteria also belongs, forms a clade within the Granofilosa.
The following species were added to the genus when it was first described in 2008:
