FIGURE 3 in Vansoestia caribensis gen. nov., sp. nov.: first report of the family Ianthellidae (Verongida, Demospongiae) in the Caribbean

FIGURE 3. Detail of the internal morphology of Vansoestia caribensis gen. nov. sp. nov. at 400–600 X. A. Ectosomal cellularized cortex, where a 1 µm cuticle (Cu) lining the outer surface of the sponge is evidenced, Scale = 13 µm. B. Various cells with inclusions (Ci1, Ci2) and smaller choanocytes (Ch) embedded in a mesohyl with abundant strands of collagen (Cs), Scale = 16 µm. C. Portion of the sponge body in contact with the substrate (Co), showing abundance of collagen strands (Cs), and cells. Notice an aquiferous canal (Ac) that is not lined by larger cells with inclusions, Scale = 25 µm. D. Detail of the mesohyl showing an aquiferous canal that is lined by cells with inclusions type 1, and "cell conglomerates" and other types of cells, Scale = 32 µm.
