Micro-computed tomography: Introducing new dimensions to taxonomy. Figure 1
Lumbrineris latreilli, a) false-colour volume rendering of the anterior region, dorso-lateral view, specimen partly covered by a thin film of ethanol; b) surface model of the vascular system (yellow) and brain (purple) superimposed on volume rendering of the worm, dorso-anterior view; c) false-colour, semi-transparent volume rendering of the anterior region, dorsal view; d) volume rendering of virtually dissected anterior region, lateral view.
Animal was fixed in formalin and preserved in 70% Ethanol. For scanning it was removed from the preservation medium and placed into a polypropylene pipette tip. Remaining liquids were removed with paper tissue and the tip was sealed to prevent drying out.
