Amoebae — Phylum Rhizopoda
Amoebae (amoeba, singular) are motile protozoans that lack flagella or cilia. Instead, these transparent blob-like creatures crawl by extending parts of their body into reaching projections, called pseudopodia (pseudo="false"; poda="foot").
Amoebae, including the arctic Actinophrys species, feed by wrapping themselves around food particles and then digesting them enzymatically – a process called phagocytosis. Arctic amoebae inhabit both marine and freshwater environments; some are parasites of the intestinal tract of humans and other vertebrates.
