Document Summary
Three general forms: asconoid, simplest, tiny pipes, syconoid. Flow go in through otium (caused by chronocytes) and out through osculum. Sponge can pump its body volume in about 5s. Slow flow = feeding: the chambers allow the water to slow down slightly. Direction of current also involved in the flow rate and suction from the corals. Help bring the sponge up off the substrate and push it up into current for filter feeding. Look at what the sponges are using and their structures to base human made structures on them since sponges undergo a lot of pressure. Mechanical stiffness is important for the sponge. The sponge derives its stiffness primarily from the sxa. The sxa"s ability to provide stiffness is limited by their resistances to. The buckling resistance of a slender structure can be increased by tapering it. Most diverse and most abundant of any other sponge groups.
