Which protozoa type is known for their ameboid movement?

Ameboid movement is characterized by the extension of pseudopodia, which are temporary projections made of cytoplasm. This type of movement is typical of amoeba, a group of protozoa that move and feed by forming these pseudopodia. Amebas can change shape and are often found in various environments, including freshwater, marine, and soil habitats.

Ciliates, on the other hand, are known for their use of hair-like structures called cilia for movement and feeding rather than pseudopodia. Flagellates utilize whip-like appendages known as flagella to propel themselves through their environment. Dinoflagellates are a distinct group primarily recognized for their unique flagellar movement and are often associated with aquatic environments, where they can cause phenomena like red tides.

Thus, the identification of ameba as the type of protozoa that exhibits ameboid movement is accurate due to its ability to use pseudopodia for locomotion and feeding.
