Taxonomy

Citation: Elatomma Haeckel 1887
Taxonomic rank: genus
Basionym: Elatomma

Catalog entries: Elatomma

Original description: Astrospharrida with one medullary (intracapsular) and one cortical (extracapsular) shell, the two being connected by radial beams piercing the central capsule. Shell surface covered with branched radial spines.

The genus Elatomma differs from Haliomma in the ramification of the radial spines, and exhibits therefore the same relation to it that Cladococcus, among the Coscinommida, bears to Acanthosphúra.
