The choanosomal skeleton is formed by bundles of styles I, pointed end uppermost, which form plumose tracts ascending through the centre of the sponge, and protruding slightly beyond the surface of the sponge. Bundles of thinner styles II and very thin oxeas line the periphery of the extra-axial skeleton, orientated tangential to the surface. Acanthose microxeas form a dense, paratangential band, around the periphery of the lower portion of the sponge and lining the spaces in the basal region of the choanosome. Microxeas are also sparsely scattered throughout the choanosome (
