Sarcomastigophora is a historical classification that was used within the taxonomic group of protozoans, specifically referring to a major group of protists characterized by their mobility through flagella and/or pseudopodia. This group is now typically split into two separate phyla: 1) Sarcodina, which includes organisms that move using pseudopodia (like amoebas), and 2) Mastigophora, which includes flagellated protozoans (like flagellates).
Key features of organisms previously classified under Sarcomastigophora include:
- Motility: Members can be motile by either flagella, cilia, or pseudopodia.
- Diversity: They encompass a wide range of organisms, from free-living to parasitic forms.
- Habitat: Found in various environments including fresh and saltwater, soil, and as parasites within hosts.
It's important to note that modern classification systems may vary, and the term Sarcomastigophora is less commonly used today as molecular techniques have provided insights that led to reclassification of numerous organisms. Instead, biologists often refer directly to the individual phyla or classes based on current taxonomic updates.
