Tissue Image: a) Perpendicular section of the body (surface above; the dark curved line crossing the lower panel is a fracture on the slide cover slip glass); b) magnification at the surface (above), subsurface (mid) and choanosome (lower) showing sterrasters and the aligned cladomes of triaenes; the lower panel is a magnification of the choanosome. Sample from the Bahamas.
