Amoebina is a suborder within the Amoebida, characterized by naked amoebae, meaning they lack a shell or test. These organisms move and feed using pseudopods. They're commonly found in soil, freshwater, and even as parasites. Think of them as the 'bare' amoebas, without any protective covering. Their flexibility allows them to squeeze into tight spaces and efficiently engulf food. Amoebina are key players in many microbial ecosystems.
