My older work “Echinodermata,” which depicts the branches of the echinoderm lineage with a cladogram in the sand, was recently used in an excellent post: Veins of Water: The Evolution of the Echinoderm Water-Vascular System, by Kevin Zelnio at Deep Sea News.
This work was also used as a backdrop in an interview with Dr. Christopher Mah (of the Smithsonian’s National Museum of Natural History and the Echinoblog).
