Most efficient sponge canal system is
Leuconoid canal system represents most complex and efficient aquiferous design characteristic of large demosponges and many calcified leucon types. Extensive folding subdivides mesohyl into myriad small spherical flagellated chambers each possessing separate prosopyle inlet and apopyle outlet connected to intricate incurrent canals delivering water and excurrent canals collecting filtered water toward multiple oscula. Enormous expansion of choanocyte surface greatly enhances pumping capacity filtering thousands litres daily supporting large body mass up to meter scale, contrasting asconoid and
