(Ussov, 1885)[1]

Polypodium is a genus of cnidarians that parasitizes in the eggs of sturgeon and similar fishes (Acipenseridae and Polyodontidae).[2] It is one of the few metazoans (animals) that live inside the cells of other animals.

Polypodium hydriforme is the only species of this monotypic genus. The parent family (Polypodiidae), order (Polypodiidea) and class (Polypodiozoa) are also monotypic.
