The extraaxial skeleton consists of several multispicular tracts (usually 2–3 megascleres) of ectosomal styles cemented by spongin, but not enclosed in sponging, running longitudinally diverging into a plumoreticulation towards the ectosome. The ectosomal skeleton has distinct brushes of ectosomal styles.
