      abstract     = {Sessile filter feeding animals, including sponges
                      (Porifera), rely on efficient fluid transport systems tokeep
                      energy expenditure for water processing low. As a
                      consequence of the sponge canal systemcomplexity only
                      limited data on flow velocities and transport rates are
                      available. This restricts ourunderstanding of this central
                      anatomical structure and related physiological processes,
                      functionalmorophological principles and ecology. Obtaining
                      experimental measurements from internal parts ofthe canal
                      system is almost impossible for most species. Therefore data
                      are mainly based ontheoretical assumptions. This is linked
                      to the limited availability of detailed morphometric
                      andquantitative data on canal system architecture. Here I
                      discuss experimental and in silico results onflow studies in
                      marine and fresh water sponges. Canal system models based on
                      SR-µCT data allowedfor the setup of finite element models
                      to study flow inside the aquiferous system and the influence
                      ofspecific canal system elements (bypasses and cellular
                      structures). In order to calibrate the model andverify
                      results flow velocity measurements by particle tracking
                      velocimetry have been performed.Observed flow velocities in
                      canal segments of diverse hierarchical orders differ from
                      predictions basedon the classical hierarchical model of flow
                      for sponges which reported much higher and fasterincreasing
                      flow velocities towards the osculum. This is a consequence
                      of the aquiferous systemarchitecture which displays a
                      compensating increase in available canal volume. With the
                      ability toactively change canal diameters and aperture
                      openings in the canal system sponges are most likelyable to
                      fine tune internal flow velocities and perfusion rates of
                      specific areas of their body.},
