Taxonomy

Citation: Sphaerozoum Meyen 1834
taxonomic rank: genus
Basionym: Sphaerozoum
Taxonomic discussion: Has been assigned to Collosphaeridae, here assigned to Sphaerozoidae following new classification being developed by Suzuki & co-workers -JY
Many species have been described (see catalog pages) but few have been subsequently reported, and no larger study of this genus has been done.  S. punctatum is almost the only species in common use - dl

Original description: Freischwimmende, kugelförmige, schleimig-gallertartige Massen, die im Innern aus Kugeln zusammengesetzt sind, welche, wiederum aus Blächen bestehen. Diese Gattung ist gleichsam ein kugelförmiges Aggregat von Individuen unsrer Physematien. Im Innern der Gallerte, welche die einzelnen Kugeln umschliesst, findet eine Ablagerung von Krystallen statt, die wahrscheinlich aus reiner Kiesel-Erde bestehen. Die Bewegung geschieht durch Contraktion der Oberfläche.
Remarks on original description: [Partly synonymized with Collozoum Haeckel by Haeckel, 1862]
