The skeleton of the choanocyte tubes consists of the same kind of small tetractines and triactines found on the cortex. The tubes are hispid because of the presence of the apical actine of the tetractines, which are more numerous (

Nevertheless, we observed that the tetractines are also present in the cortical region, and are more abundant than the small triactines. Moreover, Dendy and Frederick (1924) mentioned three categories of small triactines, while we are considering only one, which becomes sagittal and curved if positioned around the tubes or which can be folded and curved only due to bad formation.
