Their physiology depends on efficient water exchange, which is performed by the aquiferous system. This prominent poriferan anatomical character represents a dense network of incurrent and excurrent canals on which we lack detailed 3D models. To overcome this, we investigated the complex leucon-type architecture in the demosponge Tethya wilhelma using corrosion casting, microtomography, and 3D reconstructions. Our integrative qualitative and quantitative approach allowed us to create, for the first time, high-resolution 3D representations of entire canal systems which were used for detailed geometric and morphometric measurements. Canal diameters lack distinct size classes, and bifurcations are non-uniformly ramified. A relatively high number of bifurcations show previously unknown and atypical cross-sectional area ratios. Scaling properties and topological patterns of the canals indicate a more complex overall architecture than previously assumed. As a consequence, it might be more convenient to group canals into functional units rather than hierarchical clusters. Our data qualify the leucon canal system architecture of T. wilhelma as a highly efficient fluid transport system adapted toward minimal flow resistance. Our results and approach are relevant for a better understanding of sponge biology and cultivation techniques.}, cin = {DOOR / HZG}, ddc = {590}, cid = {I:(DE-H253)HAS-User-20120731 / I:(DE-H253)HZG-20120731}, pnm = {899 - ohne Topic (POF3-899) / FS-Proposal: I-20100327 (I-20100327) / FS-Proposal: I-20110915 (I-20110915)}, pid = {G:(DE-HGF)POF3-899 / G:(DE-H253)I-20100327 / G:(DE-H253)I-20110915}, experiment = {EXP:(DE-H253)D-BW2-20150101 / EXP:(DE-H253)D-W2-20150101}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000301484700003}, doi = {10.1111/j.1463-6395.2010.00492.x}, url = {https://bib-pubdb1.desy.de/record/330602}, }
