A new species of Strongylodesma Lévi, 1969 (Porifera; Demospongiae; Poecilosclerida; Latrunculiidae) from Aliwal Shoal on the east coast of South Africa Author Samaai, Toufiek Author Keyzers, Robert Author Davies-Coleman, Michael text Zootaxa 2004 584 1 11 journal article 10.5281/zenodo.157335 423aca8b-bdb1-4aa9-a785-58be9f8d6a81 1175­5326 157335 7A7D846A-F9D4-4E49-A342-0151B5674E83 Family Latrunculiidae Topsent, 1922 Diagnosis . Massive encrusting, semispherical or pedunculate sponges with areolate porefields and raised fistular oscules; texture in life soft, slightly elastic, cakey, compressed and leathery in preservative. Colour in life typically liquorice brown, dark green, olive, brown or khaki, often tinged with forest­green or blue, or rarely pale beige to white. Structural megascleres are styles or anisostrongyles, rarely oxeas, these are frequently slightly irregular, sinuous, forming a compact tangential layer under the ectosome, and a widemeshed reticulation in the choanosome. Microscleres are acanthodiscorhabds, or traditionally “chessman” spicules, bearing apical and basal whorls of spines (apical whorl and manubrium) and several crenulate discs (subsidiary and median whorls) in between, typically arranged in a compact palisade of perpendicular spicules, their bases buried in the ectosomal membrane. Viviparous. Shallow sublittoral to bathybenthic, polar to warm temperate (modified from Samaai and Kelly, 2002).
