The genus Clathria Schmidt, 1862 is the richest genus of the family Microcionidae, but only 20 species have been recorded from Brazil until now. Clathria (Axosuberites) Topsent, 1893 is characterized by having digitate, whip-like, arborescent and flabellate growth forms, lacking echinating spicules, well differentiated axial and extra-axial skeleton, styles and/or subtylostyles as principal spicules, and microscleres palmate isochelae and toxas. The subgenus contains 19 valid species, with…

TLDR
This survey revealed a high level of novelty associated with Brazilian sponge species and that distinct members responsible from the differences among Brazilian Sponge species could be correlated to the predicted functions.
