Haeckel listed amphibrachium amphilonche under the subgeneric name amphibrachidium, but did not include the subgeneric name in the species name. Varying slightly from one subclass to another, the skeletons of radiolarians are generally organized around spicules, or spines, which are sharp, dense outcroppings from the main skeletal mass The species that make up the radiolaria have numerous unique characteristics, and yet this has has not helped to elucidate a definite scheme to classify these organisms.

They may be solitary or colonial Formally they belong to the phyllum protista, subphylum sarcodina, class actinopoda, subclass radiolaria.

Radiolarian skeletons are mainly made of silica (sio₂), giving them remarkable resistance to breakdown in oceanic conditions In addition, certain species might take up trace elements or organic materials, enhancing their structural variety and aiding in their preservation within the fossil record.
