Product Description
Spumellaria is a type of Radiolaria, an aquatic protozoan life form that forms a fantastically intricate silica-containing shell. Its shell is composed of a sphere inside a sphere with multiple spikes extending to the exterior to give this planktonic creature its buoyancy in the sea.
This desk sculpture measured across from the tips of the spikes is 6.7 cm x 6.1 cm x 7.3 cm (approx. 2.75 inches in diameter).
