Micro-CT was performed to a Ceratonereis costae specimen. This sample was fixed in formalin and preserved in ethanol. Specimen was stained with 0.3% PTA dissolved in 70% ethanol. Scan was performed with a Skyscan 1172 at a voltage of 55kV and 181μΑ without filter for a full rotation of 360o. This specimen was scanned at the highest camera resolution with an exposure time of 316ms. This scan was performed for the visualisation of the internal morphology of this specimen within the framework of MAPWORMS project funded from the European Union’s Horizon Europe research and innovation programme under grant agreement N° 101046846.
