According to the original description by Ernst Haeckel, members of the family have a spherical central capsule within a fenestrated spherical siliceous shell, with two radial spines opposite in one axis. They are solitary. i.e. not associated in colonies.[1] References1. ^Report on the Radiolaria/Sphaeroidea#121 External links{{wikispecies-inline}}{{Taxonbar|from=Q16992843}}{{Radiolarian-stub}} 2 : Polycystines|Radiolarian families |
