  • Heliozoa - an overview | ScienceDirect Topics
    Heliozoa are primarily freshwater protozoa characterized by unique pseudopodia called axopodia, which are supported by microtubules and are involved in capturing food particles They are often planktonic but can also be found near the benthos, and some forms are sessile with stalks
