MicroCT data (volume rendering), LM data (surface rendering), and TEM images ( orthoslices ) combined focusing on excretory system. Volren plus voltex modules used microCT data at high transparency (low alphascale values) in AMIRA®. A–C. MicroCT data, renopericardial complex and TEM sections A. View from the left side. B. Detail of A. C. View from dorsal (anterior is to the left). D. Same as B but without renopericardial complex. E, F. MicroCT data, various organs and TEM sections. F. Detailed view from posterior. dg, digestive gland;f, foot; g, gill; gv, gill vessels; i, intestine; lk, left kidney; me, mantle edge; mu, muscle tissue; pe, pericardium; rd, renopericardial duct; rk, right kidney; rpc, renopericardial complex; vg, visceral ganglion.
