sketchfab

Micro CT scan of a Blaschka model of a sand mason worm (Lanice conchilega) from the D’Arcy Thompson Zoology Museum at the University of Dundee. DUNUC 9323 - glass model of Polychaete worm in its characteristic tube - Terebella conchilega (sand mason worm, aka Lanice conchilega). Length=13cm. The sand mason is a species of burrowing marine polychaete worm. It builds a tube which projects from the seabed, consisting of cemented sand grains and shell fragments with a fringe at the top. D’Arcy Thompson acquired a set of Blaschka’s exquistely delicate glass models in 1888. In Growth and Form, D’Arcy refers repeatedly to the art of the glass-blower, perhaps thinking of these very models. Scanned with a Nikon XT H 225ST micro CT scanner. The resulting file is exported as an stl. and imported in to Zbrush. We’d love to hear from you if you download or print our models, especially if you use them in education and outreach.
