Soleneiscidae Borojevic et al., 2002 have an essentially tubular organisation, with sponges growing in the form of an individual olynthus; several olynthi may grow from the basal stolon-like tubes, or in the form of distally branching tubes arranged radially around a central olynthus tube without any special skeletal differentiation. A continuous choanoderm lines all the internal cavities. Spicules are regular triradiates (Hooper & Wiedenmayer 1994: fig. 147) and/or quadriradiates (Hooper & Wiedenmayer 1994: fig. 158), to which tripods (Hooper & Wiedenmayer 1994: fig. 148) or biradiates (Hooper & Wiedenmayer 1994: figs 164–174) may be added.

Only two genera are included, Soleneiscus and Dendya, with both found in the Australian fauna. Soleneiscidae differ from Clathrinidae in that their adult stages consist of a simple olynthus, or olynthus-like tubes either united at their bases or distally ramified (Borojevic et al. 1990). Clathrinidae pass through the olynthus stage early in their life cycle, with subsequent growth occurring via longitudinal median division of their tubes to form anastomosing clathrate bodies, whereas Soleneiscidae maintain an olynthoid form throughout life or their tubes divide terminally forming a cormus composed of distally branched tubes.

Reviews of genera are given by Burton (1963), and discussion of the family is given by Borojevic et al. (1990, 2002).



Clathrinida with an essentially tubular organisation, forming an individual ascon tube (olynthus) with several tubes growing from the basal stolon-like tubes, or forming distally ramified but not anastomosed tubes radially arranged around a central olynthus without any special skeletal differentiation. A continuous choanoderm lines all the internal cavities. Spicules are regular triactines and/or tetractines, to which tripods or diactines may be added.
