These thin styles are also sparsely present in the surrounding mesenchyme. Toxas, none of which occur in tracts, are present in the mesenchyme and are very numerous. The spicule types present in this sponge are pictured in Text- figure 2. 1. 50m L J 25p Text-fig. 2. Spicule types present in Microciona seriata. A. Thick (= coring) styles. B. Thin style. C. Toxas. B. Adult Histology (see Table 12) Sections of adult colonies contain a dermis possessing anucleolate epidermal cells, strands of fibrous material, nucleolate cells, globoferous cells and rhabdi- ferous cells. Subdermal spaces, exhalant canals and flagellated chambers are also.
