The organism uses pseudopodia for movement, which are a defining characteristic of the Amoebozoa supergroup. It is not enclosed within a mineral shell, which rules out the Rhizaria supergroup. The presence of pseudopodia also rules out Excavata and Alveolata, which have flagella or cilia for movement. Opisthokonta encompasses fungi, animals, and certain protists, and does not seem to fit the characteristics described.
