The Fascinating World of Amoebae
Synurales Andersen 1987
Predominantely ciliated cells, benthic palmelloid colonies known; swimming cells usually with two anteriorly directed cilia – one bearing tripartite tubular hairs with short and long lateral hairs on their shafts. Cells covered with bilaterally symmetrical silica scales; eyespots absent. With statospores.

1. Synura Ehrenberg 1834
Spherical or ovoid, free-swimming colonies with loosely associated cells united by their tails in the center of colony. Each cell surrounded by a covering consisting of silica scales, their ultrastructure primarily defining the species. Cells with two cilia of almost equal length. Sometimes with amoeboid and palmella stages.
