What
Netzelia coronaObserver
bdstaylorDescription
The shell of a testate amoeba from the Mer Bleue conservation area. Specimens of Netzelia corona often form agglutinated shells, incorporating found particles. However, they can also form lumpy "tuberculate" shells composed of secreted organic material (similar to Netzelia tuberculata, which is also very common in Mer Bleue samples). This one incorporates a few large grains of sand around the aperture, but is mostly tuberculate.
Samples were air-dried and imaged in a scanning electron microscope at the Canadian Museum of Nature.
