Heliozoea

Heliozoea
A class of protozoans (subphylum Sarcodina) distinguished by stiff radiating axopodia on all sides, usually naked, though some have a skeleton of siliceous scales and spines, but without a central capsule. They are mostly fresh water dwellers, and colonial forms are common. [helio- + G. zoon, animal]
