Rigifilida is a topic that has captured the attention of millions of people around the world. With a long history and significant impact on society, Rigifilida has been the subject of debate, study and research for decades. In this article, we will explore in detail the most relevant aspects related to Rigifilida, analyzing its importance, influence and possible implications for the future. From its origin to its current evolution, Rigifilida is a topic that continues to generate interest and curiosity, and it is crucial to understand its scope to better understand the world around us.
Cells of rigifilids are covered with either a single or a double-layered submembrane pellicular lamina that makes them rigid in consistence. Slender branching filopodia emanate from a ventral aperture of the cell and are employed to collect bacteria upon which they feed and to attach the organism to the substratum. Around this aperture, the pellicle is reflexed around forming a peristomial collar.
Other notable features are flat and irregular shaped mitocondrial cristae, a single dorsal nucleus and the lack of centrioles and cilia.
