The efficacy of X-ray micro-computed tomography for acorn worm taxonomy: Balanoglossus occidentalis (manuscript species) from Puget Sound, Washington
<p>Micro-CT scan data of Balanoglossus occidentalis generated with a Zeiss Xradia Versa 520. A first scan was made of the whole specimen with AMC drift correction, 0 beam hardening, voltage of 60 kV, currant of 82 µA, exposure time of 1.7 sec, LE2 source filter, LE6 secondary filter, 1601 Projection numbers, single FOV, vertical stitching and a resolution of 9,0373 µm. Then, a second scan was made focusing on the collar and the base of the proboscis because these regions are particularly informative to taxonomic descriptions of acorn worms. This second scan had a Projection number of 2401 and a resolution of 4.5075 µm. Each scan took 3 hours.</p>
