This is rather a classic: the first virtual fly through a sponge canal system based on high resolution microtomography imaging of our pet Tethya wilhelma
. Please not that we pass through a bypass canal between the incurrent and excurrent system. We enter the sponge through the oscule (outflow opening) and leave it through an ostium (incurrent opening). The movie is also a supplement to the original publication Nickel et al. (2006) Zoomorphology 125: 209-223
