Heliozoa, commonly known as sun-animalcules, are microbial eukaryotes with stiff arms radiating from their spherical bodies, which are responsible for their common name. An amoeba is a highly motile eukaryotic, unicellular organism.Typically belonging to the kingdom protozoa, it moves in an “amoeboid” fashion.As such, microbiologists often use the term “amoeboid”, to refer to a specific type of movement and amoebae interchangeably.
