Sarcodina
Protozoans that Move with Pseudopodia
These protozoans are called Sarcodina and they move with pseudopodia. They are amoebas and are a blob of protoplasm formed in a single cell. By flowing their protoplasm forward into a "foot" then bringing the rest of their body into the foot, they can slither along. Some Sarcodina have firm axial rods instead of pseudopods. They move by motion in these rods.
