Morphology:

A typical organism of the genus Thaumatomastix is single-celled and heterotrophic, with a 15-50 micrometer body covered in siliceous scales and spines. The body scales can be triangular or elliptical plates, while the spines vary in length between species and are even bifurcated in the case of T. bipartita. The elliptical plates consist of two fused disks with a varying number of perforations, while the spines have three ridges and a collar-like structure near the proximal plate. [from wikipedia, Thaumatomastix page]

Scales are produced by silica deposition vesicles, which remain invaginated in or close to the cell’s mitochondria during their development. Once a scale is fully formed, its vesicle will move to the cell membrane to deposit it there. [from wikipedia, Thaumatomastix page]
