Wishfire 2 Posted June 9, 2008 #1579 While it is Vulcans and Romulans who have copper-based blood in the Star Trek universe, which species has blood that, when oxygenated, is the correct color of oxygenated copper-based blood? Share this post Link to post Share on other sites
Wishfire 2 Posted June 16, 2008 (edited) Copper-based blood is clear when it is non-oxygenated, and it turns blue when exposed to oxygen. So the answer I was looking for is "Andorians." Bolians also have blue blood, so if you answered "Bolians," it's a correct answer as well. 5 points. Edited June 16, 2008 by WishfireOmega Share this post Link to post Share on other sites
